# 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.
