Encode::CN - China-based Chinese Encodings
use Encode qw/encode decode/;
$euc_cn = encode("euc-cn", $utf8); # loads Encode::CN implicitly
$utf8 = decode("euc-cn", $euc_cn); # ditto
This module implements China-based Chinese charset encodings. Encodings supported are as follows.
Canonical Alias Description
--------------------------------------------------------------------
euc-cn /\beuc.*cn$/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
--------------------------------------------------------------------
To find how to use this module in detail, see the Encode manpage.
Due to size concerns, GB 18030 (an extension to GBK) is distributed
separately on CPAN, under the name the Encode::HanExtra manpage. That module
also contains extra Taiwan-based encodings.
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. See
http://www.debian.or.jp/~kubota/unicode-symbols.html.en
to find out why it is implemented that way.
