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); # dittoThis module implements China-based Chinese charset encodings. Encodings supported are as follows.

--------------------------------------------------------------------To find how to use this module in detail, see Encode.
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.
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.
