2 * Many more transliterations.
3 * GB18030 is now an alias for GB18030:2005. A new converter for GB18030:2022
4 is added. Since this encoding merely cleans up a few private-use-area
5 mappings, you can continue to use the GB18030 converter, for backward
6 compatibility. Its Unicode to GB18030 conversion direction has been
7 enhanced, to help transitioning away from PUA code points.
8 * When converting from/to an EBCDIC encoding, a non-standard way of
9 converting newlines can be requested
10 - at the C level, by calling iconvctl with argument ICONV_SET_FROM_SURFACE
11 or ICONV_SET_TO_SURFACE, or
12 - from the iconv program, by setting the environment variable
13 ICONV_EBCDIC_ZOS_UNIX to a non-empty value.
14 * Special support for z/OS: The iconv program adds a charset metadata tag to
15 its output file. (Contributed by Mike Fulton.)
18 * The libiconv library is now licensed under the LGPL version 2.1, instead of
19 the LGPL version 2.0. The iconv program continues to be licensed under GPL
21 * Added converters for many single-byte EBCDIC encodings:
22 IBM-{037,273,277,278,280,282,284,285,297,423,424,425,500,838,870,871,875},
23 IBM-{880,905,924,1025,1026,1047,1097,1112,1122,1123,1130,1132,1137,1140},
24 IBM-{1141,1142,1143,1144,1145,1146,1147,1148,1149,1153,1154,1155,1156,1157},
25 IBM-{1158,1160,1164,1165,1166,4971,12712,16804}.
26 They are available through the configure option '--enable-extra-encodings'.
29 * The preloadable library has been removed.
32 * The UTF-8 converter now rejects surrogates and out-of-range code points.
33 * Added ISO-2022-JP-MS converter.
34 * Updated the CP1255 converter to map one more character.
35 * The functions now support strings longer than 2 GB.
38 * The 'iconv' program now produces its output as soon as it can. It no longer
39 unnecessarily waits for more input.
40 * Updated the GB18030 converter to map 25 characters to code points that have
41 been to Unicode since 2000, rather than to code points in the Private Use
43 * Updated the BIG5-HKSCS converter. The old BIG5-HKSCS converter is renamed to
44 BIG5-HKSCS:2004. A new converter BIG5-HKSCS:2008 is added. BIG5-HKSCS is now
45 an alias for BIG5-HKSCS:2008.
46 * Fixed a bug in the conversion to wchar_t.
47 * Fixed a small bug in the CP1258 converter.
50 * The library and the iconv program now understand platform dependent aliases,
51 for better compatibility with the platform's own iconv_open function.
52 Examples: "646" on Solaris, "iso88591" on HP-UX, "IBM-1252" on AIX.
53 * For stateful encodings, when the input ends with a shift sequence followed
54 by invalid input, the iconv function now increments the input pointer past
55 the shift sequence before returning (size_t)(-1) with errno = EILSEQ. This
56 is also like GNU libc's iconv() behaves.
57 * The library exports a new function iconv_open_into() that stores the
58 conversion descriptor in pre-allocated memory, rather than allocating fresh
60 * Added CP1131 converter.
63 * The iconv program is now licensed under the GPL version 3, instead of the
64 GPL version 2. The libiconv library continues to be licensed under LGPL.

71 --widechar-subst that allow to specify substitutions for characters that

80 to include the Euro sign and private area characters. CP936 is no longer an
82 * Updated GB18030 converter to include all private area characters.
83 * Updated CP950 converter to include the Euro sign and private area characters.
84 * Updated CP949 converter to include private area characters.
85 * Updated the BIG5-HKSCS converter. The old BIG5-HKSCS converter is renamed to
86 BIG5-HKSCS:1999 and updated to Unicode 4. New converters BIG5-HKSCS:2001 and
87 BIG5-HKSCS:2004 are added. BIG5-HKSCS is now an alias for BIG5-HKSCS:2004.
88 * Added a few irreversible mappings to the CP932 converter.
89 * Tidy up the list of symbols exported from libiconv (assumes gcc >= 4.0).

93 * Updated the ISO-8859-7 converter.

119 * Extended the EUC-JP encoder so that YEN SIGN characters don't cause failures
120 in Shift_JIS to EUC-JP conversion.
121 * The JAVA converter now handles characters outside the Unicode BMP correctly.
122 * Fixed a bug in the CP1255, CP1258, TCVN decoders: The base characters of
123 combining characters could be dropped at the end of the conversion buffer.
124 * Fixed a bug in the transliteration that could lead to excessive memory
125 allocations in libintl when transliteration was needed.
