.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Perl 5.7.3 and later ships with an adequate set of Chinese encodings,
including the commonly used \f(CW\*(C`CP950\*(C'\fR, \f(CW\*(C`CP936\*(C'\fR (also known as \f(CW\*(C`GBK\*(C'\fR),
\&\f(CW\*(C`Big5\*(C'\fR (alias for \f(CW\*(C`Big5\-Eten\*(C'\fR), \f(CW\*(C`Big5\-HKSCS\*(C'\fR, \f(CW\*(C`EUC\-CN\*(C'\fR, \f(CW\*(C`HZ\*(C'\fR, and
\&\f(CW\*(C`ISO\-IR\-165\*(C'\fR.
.PP
However, the numbers of Chinese encodings are staggering, and a complete
coverage will easily increase the size of perl distribution by several
megabytes; hence, this \s-1CPAN\s0 module tries to provide the rest of them.
.PP
If you are using Perl 5.8 or later, Encode::CN and Encode::TW will
automatically load the extra encodings for you, so there's no need to
explicitly write \f(CW\*(C`use Encode::HanExtra\*(C'\fR if you are using one of them
already.

.PP
Detailed descriptions are as follows:
.IP "\s-1BIG5\-1984\s0" 4
.IX Item "BIG5-1984"
This is the original Big5 encoding made by \s-1TCA\s0 Taiwan.
.IP "\s-1BIG5\-2003\s0" 4
.IX Item "BIG5-2003"
This revised encoding is now national standard, as an appendix of \s-1CNS11643.\s0
.IP "\s-1BIG5PLUS\s0" 4
.IX Item "BIG5PLUS"
This encoding, while not heavily used, is an attempt to bring all Taiwan's
conflicting internal-use encodings together, and fit it as an extension to
the widely-deployed Big5 range, by \s-1CMEX\s0 Taiwan.
.IP "\s-1BIG5EXT\s0" 4
.IX Item "BIG5EXT"
The \s-1CMEX\s0's second (and less ambitious) try at unifying the most commonly
used characters not covered by Big5, while not polluting out of the 94x94
arragement like \s-1BIG5PLUS\s0 did.
.IP "\s-1CCCII\s0" 4
.IX Item "CCCII"
The earliest (and most sophisticated) Traditional Chinese encoding, with a
three-byte raw character map, made in 1980 by the Chinese Character Analysis
Group (\s-1CCAG\s0), used mostly in library systems.
.IP "EUC-TW" 4
.IX Item "EUC-TW"
The \s-1EUC\s0 transport version of \f(CW\*(C`CNS11643\*(C'\fR (planes 1\-7), the comprehensive
character set used by the Taiwan government.
.IP "CNS11643\-*" 4
.IX Item "CNS11643-*"
The raw character map extracted from the Unihan database, including the
plane F which wasn't included in \f(CW\*(C`EUC\-TW\*(C'\fR.
.IP "\s-1GB18030\s0" 4
.IX Item "GB18030"
An extension to \s-1GBK,\s0 this encoding lists most Han characters (both simplified
and traditional), as well as some other encodings used by other peoples in
China.
.IP "\s-1UNISYS\s0" 4
.IX Item "UNISYS"
Unisys System's internal Chinese mapping.
.SH "NOTES"
.IX Header "NOTES"
If you are looking for ways to transliterate between Simplified and
Traditional Chinese, please take a look at Encode::HanConvert. Note
that the direct mapping via Unicode is lossy, and usually doesn't work
at all.
.PP
Please send me suggestions if you want to see more encoding added, such
as \f(CW\*(C`BIG5\-GCCS\*(C'\fR (superseded by \f(CW\*(C`BIG5\-HKSCS\*(C'\fR). Other suggestions are welcome,
too.
