NAMEEncode::HanExtra - Extra sets of Chinese encodings
VERSIONThis 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
DESCRIPTIONPerl 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
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.
ENCODINGSThis version includes the following encoding tables:

Detailed descriptions are as follows:
This is the original Big5 encoding made by TCATaiwan.
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 CMEXTaiwan.
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 likeBIG5PLUSdid.
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 EUCtransport 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 "EUC-TW".
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.
NOTESIf 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.
