.SH "NOTES"
.IX Header "NOTES"
Due to size concerns, \f(CW\*(C`EUC\-TW\*(C'\fR (Extended Unix Character), \f(CW\*(C`CCCII\*(C'\fR
(Chinese Character Code for Information Interchange), \f(CW\*(C`BIG5PLUS\*(C'\fR
(\s-1CMEX\s0's Big5+) and \f(CW\*(C`BIG5EXT\*(C'\fR (\s-1CMEX\s0's Big5e) are distributed separately
on \s-1CPAN,\s0 under the name Encode::HanExtra. That module also contains
extra China-based encodings.
.SH "BUGS"
.IX Header "BUGS"
Since the original \f(CW\*(C`big5\*(C'\fR encoding (1984) is not supported anywhere
(glibc and DOS-based systems uses \f(CW\*(C`big5\*(C'\fR to mean \f(CW\*(C`big5\-eten\*(C'\fR; Microsoft
uses \f(CW\*(C`big5\*(C'\fR to mean \f(CW\*(C`cp950\*(C'\fR), a conscious decision was made to alias
\&\f(CW\*(C`big5\*(C'\fR to \f(CW\*(C`big5\-eten\*(C'\fR, which is the de facto superset of the original
big5.
.PP
The \f(CW\*(C`CNS11643\*(C'\fR encoding files are not complete. For common \f(CW\*(C`CNS11643\*(C'\fR
manipulation, please use \f(CW\*(C`EUC\-TW\*(C'\fR in Encode::HanExtra, which contains
planes 1\-7.
.PP
The \s-1ASCII\s0 region (0x00\-0x7f) is preserved for all encodings, even
though this conflicts with mappings by the Unicode Consortium.
