# NAME

Encode::CN - China-based Chinese Encodings

# SYNOPSIS

        use Encode qw/encode decode/;
        $euc_cn = encode("euc-cn", $utf8);   # loads Encode::CN implicitly
        $utf8   = decode("euc-cn", $euc_cn); # ditto

# DESCRIPTION

This module implements China-based Chinese charset encodings. Encodings supported are as follows.

      Canonical   Alias             Description
      --------------------------------------------------------------------
      euc-cn      /\beuc.*cn$/i     EUC (Extended Unix Character)
              /\bcn.*euc$/i
                  /\bGB[-_ ]?2312(?:\D.*$|$)/i (see below)
      gb2312-raw                    The raw (low-bit) GB2312 character map
      gb12345-raw                   Traditional chinese counterpart to
                    GB2312 (raw)
      iso-ir-165                    GB2312 + GB6345 + GB8565 + additions
      MacChineseSimp                GB2312 + Apple Additions
      cp936                         Code Page 936, also known as GBK
                    (Extended GuoBiao)
      hz                            7-bit escaped GB2312 encoding

# NOTES

Due to size concerns, "GB 18030" (an extension to "GBK") is distributed separately on CPAN, under the name Encode::HanExtra. That module also contains extra Taiwan-based encodings.

# BUGS

When you see "charset=gb2312" on mails and web pages, they really mean "euc-cn" encodings. To fix that, "gb2312" is aliased to "euc-cn". Use "gb2312-raw" when you really mean it.

The ASCII region (0x00-0x7f) is preserved for all encodings, even though this conflicts with mappings by the Unicode Consortium.
