Encode::TW - Taiwan-based Chinese Encodings
use Encode qw/encode decode/;
$big5 = encode("big5", $utf8); # loads Encode::TW implicitly
$utf8 = decode("big5", $big5); # ditto
This module implements tradition Chinese charset encodings as used in Taiwan and Hong Kong. Encodings supported are as follows.
Canonical Alias Description
--------------------------------------------------------------------
big5-eten /\bbig-?5$/i Big5 encoding (with ETen extensions)
/\bbig5-?et(en)?$/i
/\btca-?big5$/i
big5-hkscs /\bbig5-?hk(scs)?$/i
/\bhk(scs)?-?big5$/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. See
http://www.debian.or.jp/~kubota/unicode-symbols.html.en
to find out why it is implemented that way.
