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. See

to find out why it is implemented that way.
