Encode::HanExtra Perl module contains extra sets of Chinese encodings.
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
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
This version includes the following encoding tables:

Detailed descriptions are as follows:
BIG5-1984
This is the original Big5 encoding made by TCA Taiwan.
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.
