Encode::Unicode::UTF7 -- UTF-7 encoding
=head1 SYNOPSIS
use Encode qw/encode decode/;
$utf7 = encode("UTF-7", $utf8);
$utf8 = decode("UTF-7", $ucs2);
=head1 ABSTRACT
This module implements UTF-7 encoding documented in RFC 2152. UTF-7,
as its name suggests, is a 7-bit re-encoded version of UTF-16BE. It
is designed to be MTA-safe and expected to be a standard way to
exchange Unicoded mails via mails. But with the advent of UTF-8 and
8-bit compliant MTAs, UTF-7 is hardly ever used.
UTF-7 was not supported by Encode until version 1.95 because of that.
But Unicode::String, a module by Gisle Aas which adds Unicode supports
to non-utf8-savvy perl did support UTF-7, the UTF-7 support was added
so Encode can supersede Unicode::String 100%.
=head1 In Practice
When you want to encode Unicode for mails and web pages, however, do
not use UTF-7 unless you are sure your recipients and readers can
handle it. Very few MUAs and WWW Browsers support these days (only
Mozilla seems to support one). For general cases, use UTF-8 for
message body and MIME-Header for header instead.

Encode::TW - Taiwan-based Chinese Encodings
=head1 SYNOPSIS
use Encode qw/encode decode/;
$big5 = encode("big5", $utf8); # loads Encode::TW implicitly
$utf8 = decode("big5", $big5); # ditto
=head1 DESCRIPTION
This module implements tradition Chinese charset encodings as used
in Taiwan and Hong Kong.
Encodings supported are as follows.
Canonical Alias Description
--------------------------------------------------------------------
big5-eten /\bbig-?5$/i Big5 encoding (with ETen extensions)
/\bbig5-?et(en)?$/i
/\btca-?big5$/i
big5-hkscs /\bbig5-?hk(scs)?$/i
/\bhk(scs)?-?big5$/i
Big5 + Cantonese characters in Hong Kong
MacChineseTrad Big5 + Apple Vendor Mappings
cp950 Code Page 950
= Big5 + Microsoft vendor mappings
--------------------------------------------------------------------
To find out how to use this module in detail, see L<Encode>.
=head1 NOTES
Due to size concerns, C<EUC-TW> (Extended Unix Character), C<CCCII>
(Chinese Character Code for Information Interchange), C<BIG5PLUS>
(CMEX's Big5+) and C<BIG5EXT> (CMEX's Big5e) are distributed separately
on CPAN, under the name L<Encode::HanExtra>. That module also contains
extra China-based encodings.
=head1 BUGS
Since the original C<big5> encoding (1984) is not supported anywhere
(glibc and DOS-based systems uses C<big5> to mean C<big5-eten>; Microsoft
uses C<big5> to mean C<cp950>), a conscious decision was made to alias
C<big5> to C<big5-eten>, which is the de facto superset of the original
big5.
The C<CNS11643> encoding files are not complete. For common C<CNS11643>
manipulation, please use C<EUC-TW> in L<Encode::HanExtra>, which contains
planes 1-7.
The ASCII region (0x00-0x7f) is preserved for all encodings, even
though this conflicts with mappings by the Unicode Consortium.

Encode::Encoding - Encode Implementation Base Class
=head1 SYNOPSIS
package Encode::MyEncoding;
use parent qw(Encode::Encoding);
__PACKAGE__->Define(qw(myCanonical myAlias));
=head1 DESCRIPTION
As mentioned in L<Encode>, encodings are (in the current
implementation at least) defined as objects. The mapping of encoding
name to object is via the C<%Encode::Encoding> hash. Though you can
directly manipulate this hash, it is strongly encouraged to use this
base class module and add encode() and decode() methods.
=head2 Methods you should implement
You are strongly encouraged to implement methods below, at least
either encode() or decode().
=over 4
=item -E<gt>encode($string [,$check])
MUST return the octet sequence representing I<$string>.
=over 2
=item *
If I<$check> is true, it SHOULD modify I<$string> in place to remove
the converted part (i.e. the whole string unless there is an error).
If perlio_ok() is true, SHOULD becomes MUST.
=item *
If an error occurs, it SHOULD return the octet sequence for the
fragment of string that has been converted and modify $string in-place
to remove the converted part leaving it starting with the problem
fragment. If perlio_ok() is true, SHOULD becomes MUST.
=item *
If I<$check> is false then C<encode> MUST make a "best effort" to
convert the string - for example, by using a replacement character.
=back
=item -E<gt>decode($octets [,$check])
MUST return the string that I<$octets> represents.
=over 2
=item *
If I<$check> is true, it SHOULD modify I<$octets> in place to remove
the converted part (i.e. the whole sequence unless there is an
error). If perlio_ok() is true, SHOULD becomes MUST.
=item *
If an error occurs, it SHOULD return the fragment of string that has
been converted and modify $octets in-place to remove the converted
part leaving it starting with the problem fragment. If perlio_ok() is
true, SHOULD becomes MUST.
=item *
If I<$check> is false then C<decode> should make a "best effort" to
convert the string - for example by using Unicode's "\x{FFFD}" as a
replacement character.
=back
=back
If you want your encoding to work with L<encoding> pragma, you should
also implement the method below.
=over 4
=item -E<gt>cat_decode($destination, $octets, $offset, $terminator [,$check])
MUST decode I<$octets> with I<$offset> and concatenate it to I<$destination>.
Decoding will terminate when $terminator (a string) appears in output.
I<$offset> will be modified to the last $octets position at end of decode.
Returns true if $terminator appears output, else returns false.
=back
=head2 Other methods defined in Encode::Encodings
You do not have to override methods shown below unless you have to.
=over 4
=item -E<gt>name
Predefined As:
sub name { return shift->{'Name'} }
MUST return the string representing the canonical name of the encoding.
=item -E<gt>mime_name
Predefined As:
sub mime_name{
return Encode::MIME::Name::get_mime_name(shift->name);
}
MUST return the string representing the IANA charset name of the encoding.
=item -E<gt>renew
Predefined As:
sub renew {
my $self = shift;
my $clone = bless { %$self } => ref($self);
$clone->{renewed}++;
return $clone;
}
This method reconstructs the encoding object if necessary. If you need
to store the state during encoding, this is where you clone your object.
PerlIO ALWAYS calls this method to make sure it has its own private
encoding object.
=item -E<gt>renewed
Predefined As:
sub renewed { $_[0]->{renewed} || 0 }
Tells whether the object is renewed (and how many times). Some
modules emit C<Use of uninitialized value in null operation> warning
unless the value is numeric so return 0 for false.
=item -E<gt>perlio_ok()
Predefined As:
sub perlio_ok {
return eval { require PerlIO::encoding } ? 1 : 0;
}
If your encoding does not support PerlIO for some reasons, just;
sub perlio_ok { 0 }
=item -E<gt>needs_lines()
Predefined As:
sub needs_lines { 0 };
If your encoding can work with PerlIO but needs line buffering, you
MUST define this method so it returns true. 7bit ISO-2022 encodings
are one example that needs this. When this method is missing, false
is assumed.
=back
=head2 Example: Encode::ROT13
package Encode::ROT13;
use strict;
use parent qw(Encode::Encoding);
__PACKAGE__->Define('rot13');
sub encode($$;$){
my ($obj, $str, $chk) = @_;
$str =~ tr/A-Za-z/N-ZA-Mn-za-m/;
$_[1] = '' if $chk; # this is what in-place edit means
return $str;
}
# Jr pna or ynml yvxr guvf;
*decode = \&encode;
1;
=head1 Why the heck Encode API is different?
It should be noted that the I<$check> behaviour is different from the
outer public API. The logic is that the "unchecked" case is useful
when the encoding is part of a stream which may be reporting errors
(e.g. STDERR). In such cases, it is desirable to get everything
through somehow without causing additional errors which obscure the
original one. Also, the encoding is best placed to know what the
correct replacement character is, so if that is the desired behaviour
then letting low level code do it is the most efficient.
By contrast, if I<$check> is true, the scheme above allows the
encoding to do as much as it can and tell the layer above how much
that was. What is lacking at present is a mechanism to report what
went wrong. The most likely interface will be an additional method
call to the object, or perhaps (to avoid forcing per-stream objects
on otherwise stateless encodings) an additional parameter.
It is also highly desirable that encoding classes inherit from
C<Encode::Encoding> as a base class. This allows that class to define
additional behaviour for all encoding objects.
package Encode::MyEncoding;
use parent qw(Encode::Encoding);
__PACKAGE__->Define(qw(myCanonical myAlias));
to create an object with C<< bless {Name => ...}, $class >>, and call
define_encoding. They inherit their C<name> method from
C<Encode::Encoding>.
=head2 Compiled Encodings
For the sake of speed and efficiency, most of the encodings are now
supported via a I<compiled form>: XS modules generated from UCM
files. Encode provides the enc2xs tool to achieve that. Please see
L<enc2xs> for more details.
=head1 SEE ALSO
L<perlmod>, L<enc2xs>
=begin future
=over 4
=item Scheme 1
The fixup routine gets passed the remaining fragment of string being
processed. It modifies it in place to remove bytes/characters it can
understand and returns a string used to represent them. For example:
sub fixup {
my $ch = substr($_[0],0,1,'');
return sprintf("\x{%02X}",ord($ch);
}
This scheme is close to how the underlying C code for Encode works,
but gives the fixup routine very little context.
=item Scheme 2
The fixup routine gets passed the original string, an index into
it of the problem area, and the output string so far. It appends
what it wants to the output string and returns a new index into the
original string. For example:
sub fixup {
# my ($s,$i,$d) = @_;
my $ch = substr($_[0],$_[1],1);
$_[2] .= sprintf("\x{%02X}",ord($ch);
return $_[1]+1;
}
This scheme gives maximal control to the fixup routine but is more
complicated to code, and may require that the internals of Encode be tweaked to
keep the original string intact.
=item Other Schemes
Hybrids of the above.
Multiple return values rather than in-place modifications.
Index into the string could be C<pos($str)> allowing C<s/\G...//>.

When you see C<charset=ks_c_5601-1987> on mails and web pages, they really
mean "cp949" encodings. To fix that, the following aliases are set;
qr/(?:x-)?uhc$/i => '"cp949"'
qr/(?:x-)?windows-949$/i => '"cp949"'
qr/ks_c_5601-1987$/i => '"cp949"'
The ASCII region (0x00-0x7f) is preserved for all encodings, even
though this conflicts with mappings by the Unicode Consortium.

=head1 ABSTRACT
This module implements all Character Encoding Schemes of Unicode that
are officially documented by Unicode Consortium (except, of course,
for UTF-8, which is a native format in perl).
=over 4
=item L<http://www.unicode.org/glossary/> says:
I<Character Encoding Scheme> A character encoding form plus byte
serialization. There are Seven character encoding schemes in Unicode:
UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32 (UCS-4), UTF-32BE (UCS-4BE) and
UTF-32LE (UCS-4LE), and UTF-7.
Since UTF-7 is a 7-bit (re)encoded version of UTF-16BE, It is not part of
Unicode's Character Encoding Scheme. It is separately implemented in
Encode::Unicode::UTF7. For details see L<Encode::Unicode::UTF7>.

=head1 Size, Endianness, and BOM
You can categorize these CES by 3 criteria: size of each character,
endianness, and Byte Order Mark.
=head2 by size
UCS-2 is a fixed-length encoding with each character taking 16 bits.
It B<does not> support I<surrogate pairs>. When a surrogate pair
is encountered during decode(), its place is filled with \x{FFFD}
if I<CHECK> is 0, or the routine croaks if I<CHECK> is 1. When a
character whose ord value is larger than 0xFFFF is encountered,
its place is filled with \x{FFFD} if I<CHECK> is 0, or the routine
croaks if I<CHECK> is 1.
UTF-16 is almost the same as UCS-2 but it supports I<surrogate pairs>.
When it encounters a high surrogate (0xD800-0xDBFF), it fetches the
following low surrogate (0xDC00-0xDFFF) and C<desurrogate>s them to
form a character. Bogus surrogates result in death. When \x{10000}
or above is encountered during encode(), it C<ensurrogate>s them and
pushes the surrogate pair to the output stream.
UTF-32 (UCS-4) is a fixed-length encoding with each character taking 32 bits.
Since it is 32-bit, there is no need for I<surrogate pairs>.
=head2 by endianness
The first (and now failed) goal of Unicode was to map all character
repertoires into a fixed-length integer so that programmers are happy.
Since each character is either a I<short> or I<long> in C, you have to
pay attention to the endianness of each platform when you pass data
to one another.
Anything marked as BE is Big Endian (or network byte order) and LE is
Little Endian (aka VAX byte order). For anything not marked either
BE or LE, a character called Byte Order Mark (BOM) indicating the
endianness is prepended to the string.
CAVEAT: Though BOM in utf8 (\xEF\xBB\xBF) is valid, it is meaningless
and as of this writing Encode suite just leave it as is (\x{FeFF}).
=over 4
=item BOM as integer when fetched in network byte order
16 32 bits/char
-------------------------
BE 0xFeFF 0x0000FeFF
LE 0xFFFe 0xFFFe0000
-------------------------
=back
This modules handles the BOM as follows.
=over 4
=item *
When BE or LE is explicitly stated as the name of encoding, BOM is
simply treated as a normal character (ZERO WIDTH NO-BREAK SPACE).
=item *
When BE or LE is omitted during decode(), it checks if BOM is at the
beginning of the string; if one is found, the endianness is set to
what the BOM says.
=item *
Default Byte Order
When no BOM is found, Encode 2.76 and blow croaked. Since Encode
2.77, it falls back to BE accordingly to RFC2781 and the Unicode
Standard version 8.0
=item *
When BE or LE is omitted during encode(), it returns a BE-encoded
string with BOM prepended. So when you want to encode a whole text
file, make sure you encode() the whole text at once, not line by line
or each line, not file, will have a BOM prepended.
=item *
C<UCS-2> is an exception. Unlike others, this is an alias of UCS-2BE.
UCS-2 is already registered by IANA and others that way.
=back
=head1 Surrogate Pairs
To say the least, surrogate pairs were the biggest mistake of the
Unicode Consortium. But according to the late Douglas Adams in I<The
Hitchhiker's Guide to the Galaxy> Trilogy, C<In the beginning the
Universe was created. This has made a lot of people very angry and
been widely regarded as a bad move>. Their mistake was not of this
magnitude so let's forgive them.
(I don't dare make any comparison with Unicode Consortium and the
Vogons here ;) Or, comparing Encode to Babel Fish is completely
appropriate -- if you can only stick this into your ear :)
Surrogate pairs were born when the Unicode Consortium finally
admitted that 16 bits were not big enough to hold all the world's
character repertoires. But they already made UCS-2 16-bit. What
do we do?
Back then, the range 0xD800-0xDFFF was not allocated. Let's split
that range in half and use the first half to represent the C<upper
half of a character> and the second half to represent the C<lower
half of a character>. That way, you can represent 1024 * 1024 =
1048576 more characters. Now we can store character ranges up to
\x{10ffff} even with 16-bit encodings. This pair of half-character is
now called a I<surrogate pair> and UTF-16 is the name of the encoding
that embraces them.
Here is a formula to ensurrogate a Unicode character \x{10000} and
above;
$hi = ($uni - 0x10000) / 0x400 + 0xD800;
$lo = ($uni - 0x10000) % 0x400 + 0xDC00;
And to desurrogate;
$uni = 0x10000 + ($hi - 0xD800) * 0x400 + ($lo - 0xDC00);
Note this move has made \x{D800}-\x{DFFF} into a forbidden zone but
perl does not prohibit the use of characters within this range. To perl,
every one of \x{0000_0000} up to \x{ffff_ffff} (*) is I<a character>.
(*) or \x{ffff_ffff_ffff_ffff} if your perl is compiled with 64-bit
integer support!
=head1 Error Checking
Unlike most encodings which accept various ways to handle errors,
Unicode encodings simply croaks.
% perl -MEncode -e'$_ = "\xfe\xff\xd8\xd9\xda\xdb\0\n"' \
-e'Encode::from_to($_, "utf16","shift_jis", 0); print'
UTF-16:Malformed LO surrogate d8d9 at /path/to/Encode.pm line 184.
% perl -MEncode -e'$a = "BOM missing"' \
-e' Encode::from_to($a, "utf16", "shift_jis", 0); print'
UTF-16:Unrecognised BOM 424f at /path/to/Encode.pm line 184.
Unlike other encodings where mappings are not one-to-one against
Unicode, UTFs are supposed to map 100% against one another. So Encode
is more strict on UTFs.
Consider that "division by zero" of Encode :)

Encode::GSM0338 -- ESTI GSM 03.38 Encoding
=head1 SYNOPSIS
use Encode qw/encode decode/;
$gsm0338 = encode("gsm0338", $utf8); # loads Encode::GSM0338 implicitly
$utf8 = decode("gsm0338", $gsm0338); # ditto
=head1 DESCRIPTION
GSM0338 is for GSM handsets. Though it shares alphanumerals with ASCII,
control character ranges and other parts are mapped very differently,
mainly to store Greek characters. There are also escape sequences
(starting with 0x1B) to cover e.g. the Euro sign.
This was once handled by L<Encode::Bytes> but because of all those
unusual specifications, Encode 2.20 has relocated the support to
this module.
=head1 NOTES
Unlike most other encodings, the following always croaks on error
for any $chk that evaluates to true.
$gsm0338 = encode("gsm0338", $utf8 $chk);
$utf8 = decode("gsm0338", $gsm0338, $chk);
So if you want to check the validity of the encoding, surround the
expression with C<eval {}> block as follows;
eval {
$utf8 = decode("gsm0338", $gsm0338, $chk);
} or do {
# handle exception here
};
=head1 BUGS
ESTI GSM 03.38 Encoding itself.
Mapping \x00 to '@' causes too much pain everywhere.
Its use of \x1b (escape) is also very questionable.
Because of those two, the code paging approach used use in ucm-based
Encoding SOMETIMES fails so this module was written.

=head1 NOTES
Due to size concerns, C<GB 18030> (an extension to C<GBK>) is distributed
separately on CPAN, under the name L<Encode::HanExtra>. That module
also contains extra Taiwan-based encodings.
=head1 BUGS
When you see C<charset=gb2312> on mails and web pages, they really
mean C<euc-cn> encodings. To fix that, C<gb2312> is aliased to C<euc-cn>.
Use C<gb2312-raw> when you really mean it.
The ASCII region (0x00-0x7f) is preserved for all encodings, even though
this conflicts with mappings by the Unicode Consortium.

=head1 Note on ISO-2022-JP(-1)?
ISO-2022-JP-1 (RFC2237) is a superset of ISO-2022-JP (RFC1468) which
adds support for JIS X 0212-1990. That means you can use the same
code to decode to utf8 but not vice versa.
$utf8 = decode('iso-2022-jp-1', $stream);
and
$utf8 = decode('iso-2022-jp', $stream);
yield the same result but
$with_0212 = encode('iso-2022-jp-1', $utf8);
is now different from
$without_0212 = encode('iso-2022-jp', $utf8 );
In the latter case, characters that map to 0212 are first converted
to U+3013 (0xA2AE in EUC-JP; a white square also known as 'Tofu' or
'geta mark') then fed to the decoding engine. U+FFFD is not used,
in order to preserve text layout as much as possible.
=head1 BUGS
The ASCII region (0x00-0x7f) is preserved for all encodings, even
though this conflicts with mappings by the Unicode Consortium.

=head1 NAME
Encode::Guess -- Guesses encoding from data
=head1 SYNOPSIS
# if you are sure $data won't contain anything bogus
use Encode;
use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
my $utf8 = decode("Guess", $data);
my $data = encode("Guess", $utf8); # this doesn't work!
# more elaborate way
use Encode::Guess;
my $enc = guess_encoding($data, qw/euc-jp shiftjis 7bit-jis/);
ref($enc) or die "Can't guess: $enc"; # trap error this way
$utf8 = $enc->decode($data);
# or
$utf8 = decode($enc->name, $data)
=head1 ABSTRACT
Encode::Guess enables you to guess in what encoding a given data is
encoded, or at least tries to.
=head1 DESCRIPTION
By default, it checks only ascii, utf8 and UTF-16/32 with BOM.
use Encode::Guess; # ascii/utf8/BOMed UTF
To use it more practically, you have to give the names of encodings to
check (I<suspects> as follows). The name of suspects can either be
canonical names or aliases.
CAVEAT: Unlike UTF-(16|32), BOM in utf8 is NOT AUTOMATICALLY STRIPPED.
# tries all major Japanese Encodings as well
use Encode::Guess qw/euc-jp shiftjis 7bit-jis/;
If the C<$Encode::Guess::NoUTFAutoGuess> variable is set to a true
value, no heuristics will be applied to UTF8/16/32, and the result
will be limited to the suspects and C<ascii>.
=over 4
=item Encode::Guess->set_suspects
You can also change the internal suspects list via C<set_suspects>
method.
use Encode::Guess;
Encode::Guess->set_suspects(qw/euc-jp shiftjis 7bit-jis/);
=item Encode::Guess->add_suspects
Or you can use C<add_suspects> method. The difference is that
C<set_suspects> flushes the current suspects list while
C<add_suspects> adds.
use Encode::Guess;
Encode::Guess->add_suspects(qw/euc-jp shiftjis 7bit-jis/);
# now the suspects are euc-jp,shiftjis,7bit-jis, AND
# euc-kr,euc-cn, and big5-eten
Encode::Guess->add_suspects(qw/euc-kr euc-cn big5-eten/);
=item Encode::decode("Guess" ...)
When you are content with suspects list, you can now
my $utf8 = Encode::decode("Guess", $data);
=item Encode::Guess->guess($data)
But it will croak if:
=over
=item *
Two or more suspects remain
=item *
No suspects left
=back
So you should instead try this;
my $decoder = Encode::Guess->guess($data);
On success, $decoder is an object that is documented in
L<Encode::Encoding>. So you can now do this;
my $utf8 = $decoder->decode($data);
On failure, $decoder now contains an error message so the whole thing
would be as follows;
my $decoder = Encode::Guess->guess($data);
die $decoder unless ref($decoder);
my $utf8 = $decoder->decode($data);
=item guess_encoding($data, [, I<list of suspects>])
You can also try C<guess_encoding> function which is exported by
default. It takes $data to check and it also takes the list of
suspects by option. The optional suspect list is I<not reflected> to
the internal suspects list.
my $decoder = guess_encoding($data, qw/euc-jp euc-kr euc-cn/);
die $decoder unless ref($decoder);
my $utf8 = $decoder->decode($data);
# check only ascii, utf8 and UTF-(16|32) with BOM
my $decoder = guess_encoding($data);
=back
=head1 CAVEATS
=over 4
=item *
Because of the algorithm used, ISO-8859 series and other single-byte
encodings do not work well unless either one of ISO-8859 is the only
one suspect (besides ascii and utf8).
use Encode::Guess;
# perhaps ok
my $decoder = guess_encoding($data, 'latin1');
# definitely NOT ok
my $decoder = guess_encoding($data, qw/latin1 greek/);
The reason is that Encode::Guess guesses encoding by trial and error.
It first splits $data into lines and tries to decode the line for each
suspect. It keeps it going until all but one encoding is eliminated
out of suspects list. ISO-8859 series is just too successful for most
cases (because it fills almost all code points in \x00-\xff).
=item *
Do not mix national standard encodings and the corresponding vendor
encodings.
# a very bad idea
my $decoder
= guess_encoding($data, qw/shiftjis MacJapanese cp932/);
The reason is that vendor encoding is usually a superset of national
standard so it becomes too ambiguous for most cases.
=item *
On the other hand, mixing various national standard encodings
automagically works unless $data is too short to allow for guessing.
# This is ok if $data is long enough
my $decoder =
guess_encoding($data, qw/euc-cn
euc-jp shiftjis 7bit-jis
euc-kr
big5-eten/);

It is, after all, just a guess. You should alway be explicit when it
comes to encodings. But there are some, especially Japanese,
environment that guess-coding is a must. Use this module with care.

=head1 NAME
Encode::Alias - alias definitions to encodings
=head1 SYNOPSIS
use Encode;
use Encode::Alias;
define_alias( "newName" => ENCODING);
define_alias( qr/.../ => ENCODING);
define_alias( sub { return ENCODING if ...; } );
=head1 DESCRIPTION
Allows newName to be used as an alias for ENCODING. ENCODING may be
either the name of an encoding or an encoding object (as described
in L<Encode>).
Currently the first argument to define_alias() can be specified in the
following ways:
=over 4
=item As a simple string.
=item As a qr// compiled regular expression, e.g.:
define_alias( qr/^iso8859-(\d+)$/i => '"iso-8859-$1"' );
In this case, if I<ENCODING> is not a reference, it is C<eval>-ed
in order to allow C<$1> etc. to be substituted. The example is one
way to alias names as used in X11 fonts to the MIME names for the
iso-8859-* family. Note the double quotes inside the single quotes.
(or, you don't have to do this yourself because this example is predefined)
If you are using a regex here, you have to use the quotes as shown or
it won't work. Also note that regex handling is tricky even for the
experienced. Use this feature with caution.
=item As a code reference, e.g.:
define_alias( sub {shift =~ /^iso8859-(\d+)$/i ? "iso-8859-$1" : undef } );
The same effect as the example above in a different way. The coderef
takes the alias name as an argument and returns a canonical name on
success or undef if not. Note the second argument is ignored if provided.
Use this with even more caution than the regex version.
=back
=head3 Changes in code reference aliasing
As of Encode 1.87, the older form
define_alias( sub { return /^iso8859-(\d+)$/i ? "iso-8859-$1" : undef } );
no longer works.
Encode up to 1.86 internally used "local $_" to implement this older
form. But consider the code below;
use Encode;
$_ = "eeeee" ;
while (/(e)/g) {
my $utf = decode('aliased-encoding-name', $1);
print "position:",pos,"\n";
}
Prior to Encode 1.86 this fails because of "local $_".
=head2 Alias overloading
You can override predefined aliases by simply applying define_alias().
The new alias is always evaluated first, and when necessary,
define_alias() flushes the internal cache to make the new definition
available.
# redirect SHIFT_JIS to MS/IBM Code Page 932, which is a
# superset of SHIFT_JIS
define_alias( qr/shift.*jis$/i => '"cp932"' );
define_alias( qr/sjis$/i => '"cp932"' );
If you want to zap all predefined aliases, you can use
Encode::Alias->undef_aliases;
to do so. And
Encode::Alias->init_aliases;
gets the factory settings back.
Note that define_alias() will not be able to override the canonical name
of encodings. Encodings are first looked up by canonical name before
potential aliases are tried.

=cut
PK q_[�#�<p <p
Supported.podnu �[��� =head1 NAME
Encode::Supported -- Encodings supported by Encode
=head1 DESCRIPTION
=head2 Encoding Names
Encoding names are case insensitive. White space in names
is ignored. In addition, an encoding may have aliases.
Each encoding has one "canonical" name. The "canonical"
name is chosen from the names of the encoding by picking
the first in the following sequence (with a few exceptions).
=over 2
=item *
The name used by the Perl community. That includes 'utf8' and 'ascii'.
Unlike aliases, canonical names directly reach the method so such
frequently used words like 'utf8' don't need to do alias lookups.
=item *
The MIME name as defined in IETF RFCs. This includes all "iso-"s.
=item *
The name in the IANA registry.
=item *
The name used by the organization that defined it.
=back
In case I<de jure> canonical names differ from that of the Encode
module, they are always aliased if it ever be implemented. So you can
safely tell if a given encoding is implemented or not just by passing
the canonical name.
Because of all the alias issues, and because in the general case
encodings have state, "Encode" uses an encoding object internally
once an operation is in progress.
=head1 Supported Encodings
As of Perl 5.8.0, at least the following encodings are recognized.
Note that unless otherwise specified, they are all case insensitive
(via alias) and all occurrence of spaces are replaced with '-'.
In other words, "ISO 8859 1" and "iso-8859-1" are identical.
Encodings are categorized and implemented in several different modules
but you don't have to C<use Encode::XX> to make them available for
most cases. Encode.pm will automatically load those modules on demand.
=head2 Built-in Encodings
The following encodings are always available.
Canonical Aliases Comments & References
----------------------------------------------------------------
ascii US-ascii ISO-646-US [ECMA]
ascii-ctrl Special Encoding
iso-8859-1 latin1 [ISO]
null Special Encoding
utf8 UTF-8 [RFC2279]
----------------------------------------------------------------
I<null> and I<ascii-ctrl> are special. "null" fails for all character
so when you set fallback mode to PERLQQ, HTMLCREF or XMLCREF, ALL
CHARACTERS will fall back to character references. Ditto for
"ascii-ctrl" except for control characters. For fallback modes, see
L<Encode>.
=head2 Encode::Unicode -- other Unicode encodings
Unicode coding schemes other than native utf8 are supported by
Encode::Unicode, which will be autoloaded on demand.
----------------------------------------------------------------
UCS-2BE UCS-2, iso-10646-1 [IANA, UC]
UCS-2LE [UC]
UTF-16 [UC]
UTF-16BE [UC]
UTF-16LE [UC]
UTF-32 [UC]
UTF-32BE UCS-4 [UC]
UTF-32LE [UC]
UTF-7 [RFC2152]
----------------------------------------------------------------
To find how (UCS-2|UTF-(16|32))(LE|BE)? differ from one another,
see L<Encode::Unicode>.
UTF-7 is a special encoding which "re-encodes" UTF-16BE into a 7-bit
encoding. It is implemented separately by Encode::Unicode::UTF7.
=head2 Encode::Byte -- Extended ASCII
Encode::Byte implements most single-byte encodings except for
Symbols and EBCDIC. The following encodings are based on single-byte
encodings implemented as extended ASCII. Most of them map
\x80-\xff (upper half) to non-ASCII characters.
=over 2
=item ISO-8859 and corresponding vendor mappings
Since there are so many, they are presented in table format with
languages and corresponding encoding names by vendors. Note that
the table is sorted in order of ISO-8859 and the corresponding vendor
mappings are slightly different from that of ISO. See
L<http://czyborra.com/charsets/iso8859.html> for details.

=head2 gsm0338 - Hentai Latin 1
GSM0338 is for GSM handsets. Though it shares alphanumerals with
ASCII, control character ranges and other parts are mapped very
differently, mainly to store Greek characters. There are also escape
sequences (starting with 0x1B) to cover e.g. the Euro sign.
This was once handled by L<Encode::Bytes> but because of all those
unusual specifications, Encode 2.20 has relocated the support to
L<Encode::GSM0338>. See L<Encode::GSM0338> for details.
=over 2
=item gsm0338 support before 2.19
Some special cases like a trailing 0x00 byte or a lone 0x1B byte are not
well-defined and decode() will return an empty string for them.
One possible workaround is
$gsm =~ s/\x00\z/\x00\x00/;
$uni = decode("gsm0338", $gsm);
$uni .= "\xA0" if $gsm =~ /\x1B\z/;
Note that the Encode implementation of GSM0338 does not implement the
reuse of Latin capital letters as Greek capital letters (for example,
the 0x5A is U+005A (LATIN CAPITAL LETTER Z), not U+0396 (GREEK CAPITAL
LETTER ZETA).
The GSM0338 is also covered in Encode::Byte even though it is not
an "extended ASCII" encoding.

Not very popular yet. Needs Unicode Database or equivalent to
implement encode() (because it includes JIS X 0208/0212, KSC5601, and
GB2312 simultaneously, whose code points in Unicode overlap. So you
need to lookup the database to determine to what character set a given
Unicode character should belong).

Not very popular. Needs CNS 11643-1 and -2 which are not available in

=head1 Encoding vs. Charset -- terminology
We are used to using the term (character) I<encoding> and I<character
set> interchangeably. But just as confusing the terms byte and
character is dangerous and the terms should be differentiated when
needed, we need to differentiate I<encoding> and I<character set>.
To understand that, here is a description of how we make computers
grok our characters.
=over 2
=item *
First we start with which characters to include. We call this
collection of characters I<character repertoire>.
=item *
Then we have to give each character a unique ID so your computer can
tell the difference between 'a' and 'A'. This itemized character
repertoire is now a I<character set>.
=item *
If your computer can grow the character set without further
processing, you can go ahead and use it. This is called a I<coded
character set> (CCS) or I<raw character encoding>. ASCII is used this
way for most cases.
=item *
But in many cases, especially multi-byte CJK encodings, you have to
tweak a little more. Your network connection may not accept any data
with the Most Significant Bit set, and your computer may not be able to
tell if a given byte is a whole character or just half of it. So you
have to I<encode> the character set to use it.
A I<character encoding scheme> (CES) determines how to encode a given
character set, or a set of multiple character sets. 7bit ISO-2022 is
an example of a CES. You switch between character sets via I<escape
sequences>.
=back
Technically, or mathematically, speaking, a character set encoded in
such a CES that maps character by character may form a CCS. EUC is such
an example. The CES of EUC is as follows:
=over 2
=item *
Map ASCII unchanged.
=item *
Map such a character set that consists of 94 or 96 powered by N
members by adding 0x80 to each byte.
=item *
You can also use 0x8e and 0x8f to indicate that the following sequence of
characters belongs to yet another character set. To each following byte
is added the value 0x80.
=back
By carefully looking at the encoded byte sequence, you can find that the
byte sequence conforms a unique number. In that sense, EUC is a CCS
generated by a CES above from up to four CCS (complicated?). UTF-8
falls into this category. See L<perlUnicode/"UTF-8"> to find out how
UTF-8 maps Unicode to a byte sequence.
You may also have found out by now why 7bit ISO-2022 cannot comprise
a CCS. If you look at a byte sequence \x21\x21, you can't tell if
it is two !'s or IDEOGRAPHIC SPACE. EUC maps the latter to \xA1\xA1
so you have no trouble differentiating between "!!". and S<" ">.
=head1 Encoding Classification (by Anton Tagunov and Dan Kogai)
This section tries to classify the supported encodings by their
applicability for information exchange over the Internet and to
choose the most suitable aliases to name them in the context of
such communication.

US-ASCII UTF-8 ISO-8859-* KOI8-R
Shift_JIS EUC-JP ISO-2022-JP ISO-2022-JP-1
EUC-KR Big5 GB2312
are registered with IANA as preferred MIME names and may
be used over the Internet.
C<Shift_JIS> has been officialized by JIS X 0208:1997.
L<Microsoft-related naming mess> gives details.
C<GB2312> is the IANA name for C<EUC-CN>.
See L<Microsoft-related naming mess> for details.
C<GB_2312-80> I<raw> encoding is available as C<gb2312-raw>
with Encode. See L<Encode::CN> for details.
EUC-CN
KOI8-U [RFC2319]
have not been registered with IANA (as of March 2002) but
seem to be supported by major web browsers.
The IANA name for C<EUC-CN> is C<GB2312>.
KS_C_5601-1987
is heavily misused.
See L<Microsoft-related naming mess> for details.
C<KS_C_5601-1987> I<raw> encoding is available as C<kcs5601-raw>
with Encode. See L<Encode::KR> for details.
UTF-16 UTF-16BE UTF-16LE
are IANA-registered C<charset>s. See [RFC 2781] for details.
Jungshik Shin reports that UTF-16 with a BOM is well accepted
by MS IE 5/6 and NS 4/6. Beware however that
=over 2
=item *
C<UTF-16> support in any software you're going to be
using/interoperating with has probably been less tested
then C<UTF-8> support
=item *
C<UTF-8> coded data seamlessly passes traditional
command piping (C<cat>, C<more>, etc.) while C<UTF-16> coded
data is likely to cause confusion (with its zero bytes,
for example)
=item *
it is beyond the power of words to describe the way HTML browsers
encode non-C<ASCII> form data. To get a general impression, visit
L<http://www.alanflavell.org.uk/charset/form-i18n.html>.
While encoding of form data has stabilized for C<UTF-8> encoded pages
(at least IE 5/6, NS 6, and Opera 6 behave consistently), be sure to
expect fun (and cross-browser discrepancies) with C<UTF-16> encoded
pages!
=back
The rule of thumb is to use C<UTF-8> unless you know what
you're doing and unless you really benefit from using C<UTF-16>.

See L<http://lists.w3.org/Archives/Public/ietf-charsets/2001AprJun/0033.html>
for details.
Encode aliases C<KS_C_5601-1987> to C<cp949> to reflect this common
misusage. I<Raw> C<KS_C_5601-1987> encoding is available as
C<kcs5601-raw>.
See L<Encode::KR> for details.
=item GB2312
Microsoft extension to C<EUC-CN>.
Proper names: C<CP936>, C<GBK>.
C<GB2312> has been registered in the C<EUC-CN> meaning at
IANA. This has partially repaired the situation: Microsoft's
C<GB2312> has become a superset of the official C<GB2312>.
Encode aliases C<GB2312> to C<euc-cn> in full agreement with
IANA registration. C<cp936> is supported separately.
I<Raw> C<GB_2312-80> encoding is available as C<gb2312-raw>.
See L<Encode::CN> for details.
=item Big5
Microsoft extension to C<Big5>.
Proper name: C<CP950>.
Encode separately supports C<Big5> and C<cp950>.
=item Shift_JIS
Microsoft's understanding of C<Shift_JIS>.
JIS has not endorsed the full Microsoft standard however.
The official C<Shift_JIS> includes only JIS X 0201 and JIS X 0208
character sets, while Microsoft has always used C<Shift_JIS>
to encode a wider character repertoire. See C<IANA> registration for
C<Windows-31J>.
As a historical predecessor, Microsoft's variant
probably has more rights for the name, though it may be objected
that Microsoft shouldn't have used JIS as part of the name
in the first place.
Unambiguous name: C<CP932>. C<IANA> name (also used by Mozilla, and
provided as an alias by Encode): C<Windows-31J>.
Encode separately supports C<Shift_JIS> and C<cp932>.

=head1 Glossary
=over 2
=item character repertoire
A collection of unique characters. A I<character> set in the strictest
sense. At this stage, characters are not numbered.
=item coded character set (CCS)
A character set that is mapped in a way computers can use directly.
Many character encodings, including EUC, fall in this category.
=item character encoding scheme (CES)
An algorithm to map a character set to a byte sequence. You don't
have to be able to tell which character set a given byte sequence
belongs. 7-bit ISO-2022 is a CES but it cannot be a CCS. EUC is an
example of being both a CCS and CES.
=item charset (in MIME context)
has long been used in the meaning of C<encoding>, CES.
While the word combination C<character set> has lost this meaning
in MIME context since [RFC 2130], the C<charset> abbreviation has
retained it. This is how [RFC 2277] and [RFC 2278] bless C<charset>:
This document uses the term "charset" to mean a set of rules for
mapping from a sequence of octets to a sequence of characters, such
as the combination of a coded character set and a character encoding
scheme; this is also what is used as an identifier in MIME "charset="
parameters, and registered in the IANA charset registry ... (Note
that this is NOT a term used by other standards bodies, such as ISO).
[RFC 2277]
=item EUC
Extended Unix Character. See ISO-2022.
=item ISO-2022
A CES that was carefully designed to coexist with ASCII. There are a 7
bit version and an 8 bit version.
The 7 bit version switches character set via escape sequence so it
cannot form a CCS. Since this is more difficult to handle in programs
than the 8 bit version, the 7 bit version is not very popular except for
iso-2022-jp, the I<de facto> standard CES for e-mails.
The 8 bit version can form a CCS. EUC and ISO-8859 are two examples
thereof. Pre-5.6 perl could use them as string literals.
=item UCS
Short for I<Universal Character Set>. When you say just UCS, it means
I<Unicode>.
=item UCS-2
ISO/IEC 10646 encoding form: Universal Character Set coded in two
octets.
=item Unicode
A character set that aims to include all character repertoires of the
world. Many character sets in various national as well as industrial
standards have become, in a way, just subsets of Unicode.
=item UTF
Short for I<Unicode Transformation Format>. Determines how to map a
Unicode character into a byte sequence.
=item UTF-16
A UTF in 16-bit encoding. Can either be in big endian or little
endian. The big endian version is called UTF-16BE (equal to UCS-2 +
surrogate support) and the little endian version is called UTF-16LE.

=head1 ABSTRACT
This module implements L<RFC 2047|https://tools.ietf.org/html/rfc2047> MIME
encoding for an unstructured field body of the email header. It can also be
used for L<RFC 822|https://tools.ietf.org/html/rfc822> 'text' token. However,
it cannot be used directly for the whole header with the field name or for the
structured header fields like From, To, Cc, Message-Id, etc... There are 3
encoding names supported by this module: C<MIME-Header>, C<MIME-B> and
C<MIME-Q>.
=head1 DESCRIPTION
Decode method takes an unstructured field body of the email header (or
L<RFC 822|https://tools.ietf.org/html/rfc822> 'text' token) as its input and
decodes each MIME encoded-word from input string to a sequence of bytes
according to L<RFC 2047|https://tools.ietf.org/html/rfc2047> and
L<RFC 2231|https://tools.ietf.org/html/rfc2231>. Subsequently, each sequence
of bytes with the corresponding MIME charset is decoded with
L<the Encode module|Encode> and finally, one output string is returned. Text
parts of the input string which do not contain MIME encoded-word stay
unmodified in the output string. Folded newlines between two consecutive MIME
encoded-words are discarded, others are preserved in the output string.
C<MIME-B> can decode Base64 variant, C<MIME-Q> can decode Quoted-Printable
variant and C<MIME-Header> can decode both of them. If L<Encode module|Encode>
does not support particular MIME charset or chosen variant then an action based
on L<CHECK flags|Encode/Handling Malformed Data> is performed (by default, the
MIME encoded-word is not decoded).
Encode method takes a scalar string as its input and uses
L<strict UTF-8|Encode/UTF-8 vs. utf8 vs. UTF8> encoder for encoding it to UTF-8
bytes. Then a sequence of UTF-8 bytes is encoded into MIME encoded-words
(C<MIME-Header> and C<MIME-B> use a Base64 variant while C<MIME-Q> uses a
Quoted-Printable variant) where each MIME encoded-word is limited to 75
characters. MIME encoded-words are separated by C<CRLF SPACE> and joined to
one output string. Output string is suitable for unstructured field body of
the email header.
Both encode and decode methods propagate
L<CHECK flags|Encode/Handling Malformed Data> when encoding and decoding the
MIME charset.
=head1 BUGS
Versions prior to 2.22 (part of Encode 2.83) have a malfunctioning decoder
and encoder. The MIME encoder infamously inserted additional spaces or
discarded white spaces between consecutive MIME encoded-words, which led to
invalid MIME headers produced by this module. The MIME decoder had a tendency
to discard white spaces, incorrectly interpret data or attempt to decode Base64
MIME encoded-words as Quoted-Printable. These problems were fixed in version
2.22. It is highly recommended not to use any version prior 2.22!
Versions prior to 2.24 (part of Encode 2.87) ignored
L<CHECK flags|Encode/Handling Malformed Data>. The MIME encoder used
L<not strict utf8|Encode/UTF-8 vs. utf8 vs. UTF8> encoder for input Unicode
strings which could lead to invalid UTF-8 sequences. MIME decoder used also
L<not strict utf8|Encode/UTF-8 vs. utf8 vs. UTF8> decoder and additionally
called the decode method with a C<Encode::FB_PERLQQ> flag (thus user-specified
L<CHECK flags|Encode/Handling Malformed Data> were ignored). Moreover, it
automatically croaked when a MIME encoded-word contained unknown encoding.
Since version 2.24, this module uses
L<strict UTF-8|Encode/UTF-8 vs. utf8 vs. UTF8> encoder and decoder. And
L<CHECK flags|Encode/Handling Malformed Data> are correctly propagated.
Since version 2.22 (part of Encode 2.83), the MIME encoder should be fully
compliant to L<RFC 2047|https://tools.ietf.org/html/rfc2047> and
L<RFC 2231|https://tools.ietf.org/html/rfc2231>. Due to the aforementioned
bugs in previous versions of the MIME encoder, there is a I<less strict>
compatible mode for the MIME decoder which is used by default. It should be
able to decode MIME encoded-words encoded by pre 2.22 versions of this module.
However, note that this is not correct according to
L<RFC 2047|https://tools.ietf.org/html/rfc2047>.
In default I<not strict> mode the MIME decoder attempts to decode every substring
which looks like a MIME encoded-word. Therefore, the MIME encoded-words do not
need to be separated by white space. To enforce a correct I<strict> mode, set
variable C<$Encode::MIME::Header::STRICT_DECODE> to 1 e.g. by localizing:
use Encode::MIME::Header;
local $Encode::MIME::Header::STRICT_DECODE = 1;

=head1 NAME
Encode::Encoder -- Object Oriented Encoder
=head1 SYNOPSIS
use Encode::Encoder;
# Encode::encode("ISO-8859-1", $data);
Encode::Encoder->new($data)->iso_8859_1; # OOP way
# shortcut
use Encode::Encoder qw(encoder);
encoder($data)->iso_8859_1;
# you can stack them!
encoder($data)->iso_8859_1->base64; # provided base64() is defined
# you can use it as a decoder as well
encoder($base64)->bytes('base64')->latin1;
# stringified
print encoder($data)->utf8->latin1; # prints the string in latin1
# numified
encoder("\x{abcd}\x{ef}g")->utf8 == 6; # true. bytes::length($data)
=head1 ABSTRACT
B<Encode::Encoder> allows you to use Encode in an object-oriented
style. This is not only more intuitive than a functional approach,
but also handier when you want to stack encodings. Suppose you want
your UTF-8 string converted to Latin1 then Base64: you can simply say
my $base64 = encoder($utf8)->latin1->base64;
instead of
my $latin1 = encode("latin1", $utf8);
my $base64 = encode_base64($utf8);
or the lazier and more convoluted
my $base64 = encode_base64(encode("latin1", $utf8));
=head1 Description
Here is how to use this module.
=over 4
=item *
There are at least two instance variables stored in a hash reference,
{data} and {encoding}.
=item *
When there is no method, it takes the method name as the name of the
encoding and encodes the instance I<data> with I<encoding>. If successful,
the instance I<encoding> is set accordingly.
=item *
You can retrieve the result via -E<gt>data but usually you don't have to
because the stringify operator ("") is overridden to do exactly that.
=back
=head2 Predefined Methods
This module predefines the methods below:
=over 4
=item $e = Encode::Encoder-E<gt>new([$data, $encoding]);
returns an encoder object. Its data is initialized with $data if
present, and its encoding is set to $encoding if present.
When $encoding is omitted, it defaults to utf8 if $data is already in
utf8 or "" (empty string) otherwise.
=item encoder()
is an alias of Encode::Encoder-E<gt>new(). This one is exported on demand.
=item $e-E<gt>data([$data])
When $data is present, sets the instance data to $data and returns the
object itself. Otherwise, the current instance data is returned.
=item $e-E<gt>encoding([$encoding])
When $encoding is present, sets the instance encoding to $encoding and
returns the object itself. Otherwise, the current instance encoding is
returned.
=item $e-E<gt>bytes([$encoding])
decodes instance data from $encoding, or the instance encoding if
omitted. If the conversion is successful, the instance encoding
will be set to "".
The name I<bytes> was deliberately picked to avoid namespace tainting
-- this module may be used as a base class so method names that appear
in Encode::Encoding are avoided.
=back
=head2 Example: base64 transcoder
This module is designed to work with L<Encode::Encoding>.
To make the Base64 transcoder example above really work, you could
write a module like this:
package Encode::Base64;
use parent 'Encode::Encoding';
__PACKAGE__->Define('base64');
use MIME::Base64;
sub encode{
my ($obj, $data) = @_;
return encode_base64($data);
}
sub decode{
my ($obj, $data) = @_;
return decode_base64($data);
}
1;
__END__
And your caller module would be something like this:
use Encode::Encoder;
use Encode::Base64;
# now you can really do the following
encoder($data)->iso_8859_1->base64;
encoder($base64)->bytes('base64')->latin1;
=head2 Operator Overloading
This module overloads two operators, stringify ("") and numify (0+).
Stringify dumps the data inside the object.
Numify returns the number of bytes in the instance data.
They come in handy when you want to print or find the size of data.

Encode::PerlIO -- a detailed document on Encode and PerlIO
=head1 Overview
It is very common to want to do encoding transformations when
reading or writing files, network connections, pipes etc.
If Perl is configured to use the new 'perlio' IO system then
C<Encode> provides a "layer" (see L<PerlIO>) which can transform
data as it is read or written.
Here is how the blind poet would modernise the encoding:
use Encode;
open(my $iliad,'<:encoding(iso-8859-7)','iliad.greek');
open(my $utf8,'>:utf8','iliad.utf8');
my @epic = <$iliad>;
print $utf8 @epic;
close($utf8);
close($illiad);
In addition, the new IO system can also be configured to read/write
UTF-8 encoded characters (as noted above, this is efficient):
open(my $fh,'>:utf8','anything');
print $fh "Any \x{0021} string \N{SMILEY FACE}\n";
Either of the above forms of "layer" specifications can be made the default
for a lexical scope with the C<use open ...> pragma. See L<open>.
Once a handle is open, its layers can be altered using C<binmode>.
Without any such configuration, or if Perl itself is built using the
system's own IO, then write operations assume that the file handle
accepts only I<bytes> and will C<die> if a character larger than 255 is
written to the handle. When reading, each octet from the handle becomes
a byte-in-a-character. Note that this default is the same behaviour
as bytes-only languages (including Perl before v5.6) would have,
and is sufficient to handle native 8-bit encodings e.g. iso-8859-1,
EBCDIC etc. and any legacy mechanisms for handling other encodings
and binary data.
In other cases, it is the program's responsibility to transform
characters into bytes using the API above before doing writes, and to
transform the bytes read from a handle into characters before doing
"character operations" (e.g. C<lc>, C</\W+/>, ...).
You can also use PerlIO to convert larger amounts of data you don't
want to bring into memory. For example, to convert between ISO-8859-1
(Latin 1) and UTF-8 (or UTF-EBCDIC in EBCDIC machines):
open(F, "<:encoding(iso-8859-1)", "data.txt") or die $!;
open(G, ">:utf8", "data.utf") or die $!;
while (<F>) { print G }
# Could also do "print G <F>" but that would pull
# the whole file into memory just to write it out again.
More examples:
open(my $f, "<:encoding(cp1252)")
open(my $g, ">:encoding(iso-8859-2)")
open(my $h, ">:encoding(latin9)") # iso-8859-15
See also L<encoding> for how to change the default encoding of the
data in your script.
=head1 How does it work?
Here is a crude diagram of how filehandle, PerlIO, and Encode
interact.
filehandle <-> PerlIO PerlIO <-> scalar (read/printed)
\ /
Encode
When PerlIO receives data from either direction, it fills a buffer
(currently with 1024 bytes) and passes the buffer to Encode.
Encode tries to convert the valid part and passes it back to PerlIO,
leaving invalid parts (usually a partial character) in the buffer.
PerlIO then appends more data to the buffer, calls Encode again,
and so on until the data stream ends.
To do so, PerlIO always calls (de|en)code methods with CHECK set to 1.
This ensures that the method stops at the right place when it
encounters partial character. The following is what happens when
PerlIO and Encode tries to encode (from utf8) more than 1024 bytes
and the buffer boundary happens to be in the middle of a character.
A B C .... ~ \x{3000} ....
41 42 43 .... 7E e3 80 80 ....
<- buffer --------------->
<< encoded >>>>>>>>>>
<- next buffer ------
Encode converts from the beginning to \x7E, leaving \xe3 in the buffer
because it is invalid (partial character).
Unfortunately, this scheme does not work well with escape-based
encodings such as ISO-2022-JP.
=head1 Line Buffering
Now let's see what happens when you try to decode from ISO-2022-JP and
the buffer ends in the middle of a character.
JIS208-ESC \x{5f3e}
A B C .... ~ \e $ B |DAN | ....
41 42 43 .... 7E 1b 24 41 43 46 ....
<- buffer --------------------------->
<< encoded >>>>>>>>>>>>>>>>>>>>>>>
As you see, the next buffer begins with \x43. But \x43 is 'C' in
ASCII, which is wrong in this case because we are now in JISX 0208
area so it has to convert \x43\x46, not \x43. Unlike utf8 and EUC,
in escape-based encodings you can't tell if a given octet is a whole
character or just part of it.
Fortunately PerlIO also supports line buffer if you tell PerlIO to use
one instead of fixed buffer. Since ISO-2022-JP is guaranteed to revert to ASCII at the end of the line, partial
character will never happen when line buffer is used.
To tell PerlIO to use line buffer, implement -E<gt>needs_lines method
for your encoding object. See L<Encode::Encoding> for details.
Thanks to these efforts most encodings that come with Encode support
PerlIO but that still leaves following encodings.
iso-2022-kr
MIME-B
MIME-Header
MIME-Q
Fortunately iso-2022-kr is hardly used (according to Jungshik) and
MIME-* are very unlikely to be fed to PerlIO because they are for mail
headers. See L<Encode::MIME::Header> for details.
=head2 How can I tell whether my encoding fully supports PerlIO ?
As of this writing, any encoding whose class belongs to Encode::XS and
Encode::Unicode works. The Encode module has a C<perlio_ok> method
which you can use before applying PerlIO encoding to the filehandle.
Here is an example:
my $use_perlio = perlio_ok($enc);
my $layer = $use_perlio ? "<:raw" : "<:encoding($enc)";
open my $fh, $layer, $file or die "$file : $!";
while(<$fh>){
$_ = decode($enc, $_) unless $use_perlio;
# ....
}
