1.1 misho 1: GNU LIBICONV - character set conversion library
2:
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.
5:
6: It provides support for the encodings:
7:
8: European languages
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},
14: Macintosh
15: Semitic languages
16: ISO-8859-{6,8}, CP{1255,1256}, CP862, Mac{Hebrew,Arabic}
17: Japanese
18: EUC-JP, SHIFT_JIS, CP932, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-1

24: Armenian
25: ARMSCII-8
26: Georgian
27: Georgian-Academy, Georgian-PS
28: Tajik
29: KOI8-T
30: Kazakh
31: PT154, RK1048
32: Thai
33: ISO-8859-11, TIS-620, CP874, MacThai
34: Laotian
35: MuleLao-1, CP1133
36: Vietnamese
37: VISCII, TCVN, CP1258
38: Platform specifics
39: HP-ROMAN8, NEXTSTEP
40: Full Unicode
41: UTF-8
42: UCS-2, UCS-2BE, UCS-2LE
43: UCS-4, UCS-4BE, UCS-4LE
44: UTF-16, UTF-16BE, UTF-16LE
45: UTF-32, UTF-32BE, UTF-32LE
46: UTF-7
47: C99, JAVA
48: Full Unicode, in terms of `uint16_t' or `uint32_t'
49: (with machine dependent endianness and alignment)
50: UCS-2-INTERNAL, UCS-4-INTERNAL
51: Locale dependent, in terms of `char' or `wchar_t'
52: (with machine dependent endianness and alignment, and with OS and
53: locale dependent semantics)
54: char, wchar_t
55: The empty encoding name "" is equivalent to "char": it denotes the
56: locale dependent character encoding.
57:
58: When configured with the option --enable-extra-encodings, it also provides
59: support for a few extra encodings:
60:
61: European languages
62: CP{437,737,775,852,853,855,857,858,860,861,863,865,869,1125}
63: Semitic languages
64: CP864
65: Japanese
66: EUC-JISX0213, Shift_JISX0213, ISO-2022-JP-3
67: Chinese
68: BIG5-2003 (experimental)
69: Turkmen
70: TDS565
71: Platform specifics
72: ATARIST, RISCOS-LATIN1
73:
74: It can convert from any of these encodings to any other, through Unicode
75: conversion.
76:
77: It has also some limited support for transliteration, i.e. when a character
78: cannot be represented in the target character set, it can be approximated
79: through one or several similarly looking characters. Transliteration is
80: activated when "//TRANSLIT" is appended to the target encoding name.
81:
82: libiconv is for you if your application needs to support multiple character
83: encodings, but that support lacks from your system.
84:

86: Installation
87: ------------
88:
89: As usual for GNU packages:
90:
91: $ ./configure --prefix=/usr/local
92: $ make
93: $ make install
94:
95: After installing GNU libiconv for the first time, it is recommended to
96: recompile and reinstall GNU gettext, so that it can take advantage of
97: libiconv.
98:
99: On systems other than GNU/Linux, the iconv program will be internationalized
100: only if GNU gettext has been built and installed before GNU libiconv. This
101: means that the first time GNU libiconv is installed, we have a circular
102: dependency between the GNU libiconv and GNU gettext packages, which can be
103: resolved by building and installing either
104: - first libiconv, then gettext, then libiconv again,
105: or (on systems supporting shared libraries, excluding AIX)
106: - first gettext, then libiconv, then gettext again.
107: Recall that before building a package for the second time, you need to erase
108: the traces of the first build by running "make distclean".
109:
110: This library can be built and installed in two variants:
111:
112: - The library mode. This works on all systems, and uses a library
113: `libiconv.so' and a header file `<iconv.h>'. (Both are installed
114: through "make install".)
115:
116: To use it, simply #include <iconv.h> and use the functions.
117:
118: To use it in an autoconfiguring package:
119: - If you don't use automake, append m4/iconv.m4 to your aclocal.m4
120: file.
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 the GNU gettext package, which
127: installs it in /usr/local/share/aclocal/iconv.m4.
128:
129: - The libc plug/override mode. This works on GNU/Linux, Solaris and OSF/1
130: systems only. It is a way to get good iconv support without having
131: glibc-2.1.
132: It installs a library `preloadable_libiconv.so'. This library can be used
133: with LD_PRELOAD, to override the iconv* functions present in the C library.
134:
135: On GNU/Linux and Solaris:
136: $ export LD_PRELOAD=/usr/local/lib/preloadable_libiconv.so
137:
138: On OSF/1:
139: $ export _RLD_LIST=/usr/local/lib/preloadable_libiconv.so:DEFAULT
140:
141: A program's source need not be modified, the program need not even be
142: recompiled. Just set the LD_PRELOAD environment variable, that's it!
