NAME
       Encode::TW - Taiwan-based Chinese Encodings

SYNOPSIS
           use Encode qw/encode decode/;
           $big5 = encode("big5", $utf8); # loads Encode::TW implicitly
           $utf8 = decode("big5", $big5); # ditto

DESCRIPTION
       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

NOTES
       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.

BUGS
       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.
