1 GNU LIBICONV - character set conversion library
3 This library provides an iconv() implementation, for use on systems which
4 don't have one, or whose implementation cannot convert from/to Unicode.
6 It provides support for the encodings:
9 ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16},
10 KOI8-R, KOI8-U, KOI8-RU,
11 CP{1250,1251,1252,1253,1254,1257}, CP{850,866,1131},
12 Mac{Roman,CentralEurope,Iceland,Croatian,Romania},
13 Mac{Cyrillic,Ukraine,Greek,Turkish},
16 ISO-8859-{6,8}, CP{1255,1256}, CP862, Mac{Hebrew,Arabic}
18 EUC-JP, SHIFT_JIS, CP932, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-1,
21 EUC-CN, HZ, GBK, CP936, GB18030, EUC-TW, BIG5, CP950, BIG5-HKSCS,
22 BIG5-HKSCS:2004, BIG5-HKSCS:2001, BIG5-HKSCS:1999, ISO-2022-CN,
25 EUC-KR, CP949, ISO-2022-KR, JOHAB
29 Georgian-Academy, Georgian-PS
35 ISO-8859-11, TIS-620, CP874, MacThai
44 UCS-2, UCS-2BE, UCS-2LE
45 UCS-4, UCS-4BE, UCS-4LE
46 UTF-16, UTF-16BE, UTF-16LE
47 UTF-32, UTF-32BE, UTF-32LE
50 Full Unicode, in terms of 'uint16_t' or 'uint32_t'
51 (with machine dependent endianness and alignment)
52 UCS-2-INTERNAL, UCS-4-INTERNAL
53 Locale dependent, in terms of 'char' or 'wchar_t'
54 (with machine dependent endianness and alignment, and with OS and
55 locale dependent semantics)
57 The empty encoding name "" is equivalent to "char": it denotes the
58 locale dependent character encoding.
60 When configured with the option --enable-extra-encodings, it also provides
61 support for a few extra encodings:
64 CP{437,737,775,852,853,855,857,858,860,861,863,865,869,1125}
68 EUC-JISX0213, Shift_JISX0213, ISO-2022-JP-3
70 BIG5-2003 (experimental)
74 ATARIST, RISCOS-LATIN1
76 It can convert from any of these encodings to any other, through Unicode
79 It has also some limited support for transliteration, i.e. when a character
80 cannot be represented in the target character set, it can be approximated
81 through one or several similarly looking characters. Transliteration is
82 activated when "//TRANSLIT" is appended to the target encoding name.
84 libiconv is for you if your application needs to support multiple character
85 encodings, but that support lacks from your system.
91 As usual for GNU packages:
93 $ ./configure --prefix=[[PREFIX]] where [[PREFIX]] is e.g. $HOME/local
97 After installing GNU libiconv for the first time, it is recommended to
98 recompile and reinstall GNU gettext, so that it can take advantage of
101 On systems other than GNU/Linux, the iconv program will be internationalized
102 only if GNU gettext has been built and installed before GNU libiconv. This
103 means that the first time GNU libiconv is installed, we have a circular
104 dependency between the GNU libiconv and GNU gettext packages, which can be
105 resolved by building and installing either
106 - first libiconv, then gettext, then libiconv again,
107 or (on systems supporting shared libraries, excluding AIX)
108 - first gettext, then libiconv, then gettext again.
109 Recall that before building a package for the second time, you need to erase
110 the traces of the first build by running "make distclean".
112 This library installs:
113 - a library 'libiconv.so',
114 - a header file '<iconv.h>'.
116 To use it, simply #include <iconv.h> and use the functions.
118 To use it in an autoconfiguring package:
119 - If you don't use automake, append m4/iconv.m4 to your aclocal.m4
121 - If you do use automake, add m4/iconv.m4 to your m4 macro repository.
122 - Add to the link command line of libraries and executables that use
123 the functions the placeholder @LIBICONV@ (or, if using libtool for
124 the link, @LTLIBICONV@). If you use automake, the right place for
125 these additions are the *_LDADD variables.
126 Note that 'iconv.m4' is also part of GNU gnulib, available through
127 the gnulib module 'iconv'.
133 The libiconv and libcharset _libraries_ and their header files are under LGPL,
134 see file COPYING.LIB.
136 The iconv _program_ and the documentation are under GPL, see file COPYING.
