Encode::HanExtra(3pm)
NAME
Encode::HanExtra - Extra sets of Chinese encodings
VERSION
This document describes version 0.23 of Encode::HanExtra, released
November 10, 2007.
SYNOPSIS
use Encode;
# Traditional Chinese
$euc_tw = encode("euc-tw", $utf8); # loads Encode::HanExtra implicitly
$utf8 = decode("euc-tw", $euc_tw); # ditto
# Simplified Chinese
$gb18030 = encode("gb18030", $utf8); # loads Encode::HanExtra implicitly
$utf8 = decode("gb18030", $gb18030); # ditto
DESCRIPTION
Perl 5.7.3 and later ships with an adequate set of Chinese encodings,
including the commonly used "CP950", "CP936" (also known as "GBK"),
"Big5" (alias for "Big5-Eten"), "Big5-HKSCS", "EUC-CN", "HZ", and
"ISO-IR-165".
However, the numbers of Chinese encodings are staggering, and a
complete coverage will easily increase the size of perl distribution by
several megabytes; hence, this CPAN module tries to provide the rest of
them.
If you are using Perl 5.8 or later, Encode::CN and Encode::TW will
automatically load the extra encodings for you, so there's no need to
explicitly write "use Encode::HanExtra" if you are using one of them
already.
ENCODINGS

- Detailed descriptions are as follows:
- BIG5-1984
- This is the original Big5 encoding made by TCA Taiwan.
- BIG5-2003
- This revised encoding is now national standard, as an appendix of
CNS11643. - BIG5PLUS
- This encoding, while not heavily used, is an attempt to bring all
Taiwan's conflicting internal-use encodings together, and fit it as an extension to the widely-deployed Big5 range, by CMEX Taiwan. - BIG5EXT
- The CMEX's second (and less ambitious) try at unifying the most
commonly used characters not covered by Big5, while not polluting
out of the 94x94 arragement like BIG5PLUS did. - CCCII
- The earliest (and most sophisticated) Traditional Chinese encoding,
with a three-byte raw character map, made in 1980 by the Chinese
Character Analysis Group (CCAG), used mostly in library systems. - EUC-TW
- The EUC transport version of "CNS11643" (planes 1-7), the
comprehensive character set used by the Taiwan government. - CNS11643-*
- The raw character map extracted from the Unihan database, including the plane F which wasn't included in "EUC-TW".
- GB18030
- An extension to GBK, this encoding lists most Han characters (both
simplified and traditional), as well as some other encodings used
by other peoples in China. - UNISYS
- Unisys System's internal Chinese mapping.
NOTES
If you are looking for ways to transliterate between Simplified and
Traditional Chinese, please take a look at Encode::HanConvert. Note
that the direct mapping via Unicode is lossy, and usually doesn't work
at all.
Please send me suggestions if you want to see more encoding added, such
as "BIG5-GCCS" (superseded by "BIG5-HKSCS"). Other suggestions are
welcome, too.
