Encode::TW − Taiwan−based Chinese Encodings
use Encode qw/encode decode/;
$big5 = encode("big5", $utf8); # loads Encode::TW implicitly
$utf8 = decode("big5", $big5); # ditto
This module implements tradition Chinese charset encodings as used in Taiwan and Hong Kong. Encodings supported are as follows.
Canonical Alias Description
big5−eten / big−?5$/i Big5 encoding (with ETen extensions)
big5−hkscs / big5−?hk(scs)?$/i
Big5 + Cantonese characters in Hong Kong
MacChineseTrad Big5 + Apple Vendor Mappings
cp950 Code Page 950
= Big5 + Microsoft vendor mappings
To find out how to use this module in detail, see Encode.
Due to size concerns, "EUC−TW" (Extended Unix Character), "CCCII" (Chinese Character Code for Information Interchange), "BIG5PLUS" ( CMEX ’s Big5+) and "BIG5EXT" ( CMEX ’s Big5e) are distributed separately on CPAN , under the name Encode::HanExtra. That module also contains extra China-based encodings.
Since the original "big5" encoding (1984) is not supported anywhere (glibc and DOS-based systems uses "big5" to mean "big5−eten"; Microsoft uses "big5" to mean "cp950"), a conscious decision was made to alias "big5" to "big5−eten", which is the de facto superset of the original big5.
The "CNS11643" encoding files are not complete. For common "CNS11643" manipulation, please use "EUC−TW" in Encode::HanExtra, which contains planes 1−7.
The ASCII region (0x00−0x7f) is preserved for all encodings, even though this conflicts with mappings by the Unicode Consortium.
