Encode hackers,
With Encode-1.00 released, I felt like a more casual programming so I
came up with Charset-0.01. I'll just post a pod2text-rendered doc to
show you how it is like. My favorite is a one-liner from shell script.

NAME
Charset - write perl codes in any encodings you like
SYNOPSIS
use Charset "euc-jp"; # Jperl!
#...
sub tricky_part{
no Charset;
#...
}
use Charset "euc-jp"; # restore the state; Filter::Simple bug.
# Handy for EUC-JP => UTF-8 converter
# when your text editor only supports Shift_JIS !
use Charset "shiftjis", IN => "euc-jp", OUT => "utf8";
# If your shell supports EUC-JP, you can even do this!
perl -MCharset=euc-jp 'print "Nihongo\n" x 4'
ABSTRACT
This module allows you to write your perl codes in not only ASCII (or
EBCDIC where your environment allows) or UTF-8 but any character
encodings that Encode module supports.
USAGE
First argument to the "use" line must be the name of encoding which
matches your script. It croaks if none specified or the one
specified is
unsupported by the Encode module.
You can optionally feed the argument in hash. The followin options
are
supported.
STDIN => *enc_name*
Sets the discipline of STDIN to ":encoding(*enc_name*)". By
default,
the same encoding as the caller script is used.
STDOUT => *enc_name*
Sets the discipline of STDOUT to ":encoding(*enc_name*)". By
default, the same encoding as the caller script is used.
IN => *enc_name*
Internally does "use open IN => ":encoding(*enc_name*)"". No
default
is set. See open.
OUT => *enc_name*
Internally does "use open OUT => ":encoding(*enc_name*)"". No
default is set. See open.
IO => *enc_name*
Internally does "use open IO => ":encoding(*enc_name*)"". No
default
is set. IN or OUT overrides this setting.
DESCRIPTION
This is a technology demonstrator of Perl 5.8.0. It uses Encode and
Filter::Util::Call, both of which will be inlucuded in perl
distribution.
Before perl 5.6.0, a character means a byte. Though it was possible
to
include literals in multibyte characters in certain encodings (such
as
EUC-JP), You needed to handle them with care. Some encodings didn't
even
allow this (such as Shift_JIS) and you needed things like Jperl to do
that. If your multibyte encoding was not Japanese, you were out of
luck.
As of Perl 5.6.0, you could use UTF-8 strings internally so you could
apply everything you wanted to do to multilingual string, including
regexes. You could even use UTF-8 string for identifiers you could go
like
my $Ren++; # "Ren" is really a U+4EBA
to make a child :) But there was one precondition. Your source file
must
be in UTF-8. With decent text editors and environments that can
handle
UTF-8 was rare (and still is to some extent), You still needed
character
encoding converters like Jcode.pm
With perl 5.8.0 and this module, this will all change. Your old
script
in your regional character encoding suddenly starts working just by
adding
use Charset qw(your-encoding);
BUGS
This modules uses Filter::Simple. So it is subject to the limitation
of
Filter::Simple. Filter::Simple and Text::Balance which Filter::Simple
uses does a pretty good job for block detection
