GNU LIBICONV - character set conversion library
This library provides an iconv() implementation, for use on systems which
don't have one, or whose implementation cannot convert from/to Unicode.
It provides support for the encodings:
European languages
ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16},
KOI8-R, KOI8-U, KOI8-RU,
CP{1250,1251,1252,1253,1254,1257}, CP{850,866,1131},
Mac{Roman,CentralEurope,Iceland,Croatian,Romania},
Mac{Cyrillic,Ukraine,Greek,Turkish},
Macintosh
Semitic languages
ISO-8859-{6,8}, CP{1255,1256}, CP862, Mac{Hebrew,Arabic}
Japanese
EUC-JP, SHIFT_JIS, CP932, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-1,
ISO-2022-JP-MS
Chinese
EUC-CN, HZ, GBK, CP936, GB18030, EUC-TW, BIG5, CP950, BIG5-HKSCS,
BIG5-HKSCS:2004, BIG5-HKSCS:2001, BIG5-HKSCS:1999, ISO-2022-CN,
ISO-2022-CN-EXT
Korean
EUC-KR, CP949, ISO-2022-KR, JOHAB
Armenian
ARMSCII-8
Georgian
Georgian-Academy, Georgian-PS
Tajik
KOI8-T
Kazakh
PT154, RK1048
Thai
ISO-8859-11, TIS-620, CP874, MacThai
Laotian
MuleLao-1, CP1133
Vietnamese
VISCII, TCVN, CP1258
Platform specifics
HP-ROMAN8, NEXTSTEP
Full Unicode
UTF-8
UCS-2, UCS-2BE, UCS-2LE
UCS-4, UCS-4BE, UCS-4LE
UTF-16, UTF-16BE, UTF-16LE
UTF-32, UTF-32BE, UTF-32LE
UTF-7
C99, JAVA
Full Unicode, in terms of 'uint16_t' or 'uint32_t'
(with machine dependent endianness and alignment)
UCS-2-INTERNAL, UCS-4-INTERNAL
Locale dependent, in terms of 'char' or 'wchar_t'
(with machine dependent endianness and alignment, and with OS and
locale dependent semantics)
char, wchar_t
The empty encoding name "" is equivalent to "char": it denotes the
locale dependent character encoding.
When configured with the option --enable-extra-encodings, it also provides
support for a few extra encodings:
European languages
CP{437,737,775,852,853,855,857,858,860,861,863,865,869,1125}
Semitic languages
CP864
Japanese
EUC-JISX0213, Shift_JISX0213, ISO-2022-JP-3
Chinese
BIG5-2003 (experimental)
Turkmen
TDS565
Platform specifics
ATARIST, RISCOS-LATIN1
EBCDIC compatible (not ASCII compatible, very rarely used)
European languages
IBM-{037,273,277,278,280,282,284,285,297,423,500,870,871,875,880},
IBM-{905,924,1025,1026,1047,1112,1122,1123,1140,1141,1142,1143},

Persian
IBM-1097
Thai
IBM-{838,1160}
Laotian
IBM-1132
Vietnamese
IBM-{1130,1164}
Indic languages
IBM-1137
It can convert from any of these encodings to any other, through Unicode
conversion.
It has also some limited support for transliteration, i.e. when a character
cannot be represented in the target character set, it can be approximated
through one or several similarly looking characters. Transliteration is
activated when "//TRANSLIT" is appended to the target encoding name.
libiconv is for you if your application needs to support multiple character
encodings, but that support lacks from your system.
Installation
------------
As usual for GNU packages:
$ ./configure --prefix=[[PREFIX]] where [[PREFIX]] is e.g. $HOME/local
$ make
$ make install
After installing GNU libiconv for the first time, it is recommended to
recompile and reinstall GNU gettext, so that it can take advantage of
libiconv.
On systems other than GNU/Linux, the iconv program will be internationalized
only if GNU gettext has been built and installed before GNU libiconv. This
means that the first time GNU libiconv is installed, we have a circular
dependency between the GNU libiconv and GNU gettext packages, which can be
resolved by building and installing either
- first libiconv, then gettext, then libiconv again,
or (on systems supporting shared libraries, excluding AIX)
- first gettext, then libiconv, then gettext again.
Recall that before building a package for the second time, you need to erase
the traces of the first build by running "make distclean".
This library installs:
- a library 'libiconv.so',
- a header file '<iconv.h>'.
To use it, simply #include <iconv.h> and use the functions.
To use it in a package that uses GNU autoconf and GNU automake:
- Use gnulib-tool to import the Gnulib module 'iconv'. It consists
of a couple of *.m4 files (iconv.m4 and its dependencies) and a
file 'build-aux/config.rpath'.
- Add to the link command line of libraries and executables that use
the functions the placeholder @LIBICONV@ (or, if using libtool for
the link, @LTLIBICONV@). In Makefile.am files, the right place for
these additions are the *_LDADD variables.
