Encode::HanExtra - Extra sets of Chinese encodings
This document describes version 0.23 of Encode::HanExtra, released November 10, 2007.
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
CP936(also known as
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::HanExtraif you are using one of them already.
This version includes the following encoding tables:

Detailed descriptions are as follows:
This is the original Big5 encoding made by TCA Taiwan.
This revised encoding is now national standard, as an appendix of CNS11643.
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.
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.
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.
The EUC transport version of
CNS11643(planes 1-7), the comprehensive character set used by the Taiwan government.
The raw character map extracted from the Unihan database, including the plane F which wasn't included in
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 System's internal Chinese mapping.
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-HKSCS). Other suggestions are welcome, too.
