6 Encode::HanExtra - Extra sets of Chinese encodings

9 This document describes version 0.23 of Encode::HanExtra, released
10 November 10, 2007.

13 use Encode;
14 # Traditional Chinese
16 $euc_tw = encode("euc-tw", $utf8); # loads Encode::HanExtra implicitly
17 $utf8 = decode("euc-tw", $euc_tw); # ditto
18 # Simplified Chinese
20 $gb18030 = encode("gb18030", $utf8); # loads Encode::HanExtra implicitly
21 $utf8 = decode("gb18030", $gb18030); # ditto

24 Perl 5.7.3 and later ships with an adequate set of Chinese encodings,
25 including the commonly used "CP950", "CP936" (also known as "GBK"),
26 "Big5" (alias for "Big5-Eten"), "Big5-HKSCS", "EUC-CN", "HZ", and
27 "ISO-IR-165".
28 However, the numbers of Chinese encodings are staggering, and a
30 complete coverage will easily increase the size of perl distribution by
31 several megabytes; hence, this CPAN module tries to provide the rest of
32 them.
33 If you are using Perl 5.8 or later, Encode::CN and Encode::TW will
35 automatically load the extra encodings for you, so there's no need to
36 explicitly write "use Encode::HanExtra" if you are using one of them
37 already.

40 This version includes the following encoding tables:

65 Detailed descriptions are as follows:
67 BIG5-1984
69 This is the original Big5 encoding made by TCA Taiwan.
70 BIG5-2003
72 This revised encoding is now national standard, as an appendix of
73 CNS11643.
74 BIG5PLUS
76 This encoding, while not heavily used, is an attempt to bring all
77 Taiwan's conflicting internal-use encodings together, and fit it as
78 an extension to the widely-deployed Big5 range, by CMEX Taiwan.
79 BIG5EXT
81 The CMEX's second (and less ambitious) try at unifying the most
82 commonly used characters not covered by Big5, while not polluting
83 out of the 94x94 arragement like BIG5PLUS did.
84 CCCII
86 The earliest (and most sophisticated) Traditional Chinese encoding,
87 with a three-byte raw character map, made in 1980 by the Chinese
88 Character Analysis Group (CCAG), used mostly in library systems.
89 EUC-TW
91 The EUC transport version of "CNS11643" (planes 1-7), the
92 comprehensive character set used by the Taiwan government.
93 CNS11643-*
95 The raw character map extracted from the Unihan database, including
96 the plane F which wasn't included in "EUC-TW".
97 GB18030
99 An extension to GBK, this encoding lists most Han characters (both
100 simplified and traditional), as well as some other encodings used
101 by other peoples in China.
102 UNISYS
104 Unisys System's internal Chinese mapping.
105
107 If you are looking for ways to transliterate between Simplified and
108 Traditional Chinese, please take a look at Encode::HanConvert. Note
109 that the direct mapping via Unicode is lossy, and usually doesn't work
110 at all.
111 Please send me suggestions if you want to see more encoding added, such
113 as "BIG5-GCCS" (superseded by "BIG5-HKSCS"). Other suggestions are
114 welcome, too.
