.SH "NOTES"
.IX Header "NOTES"
Due to size concerns, \f(CW\*(C`GB 18030\*(C'\fR (an extension to \f(CW\*(C`GBK\*(C'\fR) is distributed
separately on \s-1CPAN\s0, under the name Encode::HanExtra. That module
also contains extra Taiwan-based encodings.
.SH "BUGS"
.IX Header "BUGS"
When you see \f(CW\*(C`charset=gb2312\*(C'\fR on mails and web pages, they really
mean \f(CW\*(C`euc\-cn\*(C'\fR encodings.  To fix that, \f(CW\*(C`gb2312\*(C'\fR is aliased to \f(CW\*(C`euc\-cn\*(C'\fR.
Use \f(CW\*(C`gb2312\-raw\*(C'\fR when you really mean it.
.PP
The \s-1ASCII\s0 region (0x00\-0x7f) is preserved for all encodings, even though
this conflicts with mappings by the Unicode Consortium.  See
.PP
<http://www.debian.or.jp/~kubota/unicode\-symbols.html.en>

to find out why it is implemented that way.
