| 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}, |
| 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 |
| Chinese |
| EUC-CN, HZ, GBK, CP936, GB18030, EUC-TW, BIG5, CP950, BIG5-HKSCS, |
| 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 |
| 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 |
| |
| 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=/usr/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 can be built and installed in two variants: |
| |
| - The library mode. This works on all systems, and uses a library |
| `libiconv.so' and a header file `<iconv.h>'. (Both are installed |
| through "make install".) |
| |
| To use it, simply #include <iconv.h> and use the functions. |
| |
| To use it in an autoconfiguring package: |
| - If you don't use automake, append m4/iconv.m4 to your aclocal.m4 |
| file. |
| - If you do use automake, add m4/iconv.m4 to your m4 macro repository. |
| - 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@). If you use automake, the right place for |
| these additions are the *_LDADD variables. |
| Note that 'iconv.m4' is also part of the GNU gettext package, which |
| installs it in /usr/local/share/aclocal/iconv.m4. |
| |
| - The libc plug/override mode. This works on GNU/Linux, Solaris and OSF/1 |
| systems only. It is a way to get good iconv support without having |
| glibc-2.1. |
| It installs a library `preloadable_libiconv.so'. This library can be used |
| with LD_PRELOAD, to override the iconv* functions present in the C library. |
| |
| On GNU/Linux and Solaris: |
| $ export LD_PRELOAD=/usr/local/lib/preloadable_libiconv.so |
| |
| On OSF/1: |
| $ export _RLD_LIST=/usr/local/lib/preloadable_libiconv.so:DEFAULT |
| |
| A program's source need not be modified, the program need not even be |
| recompiled. Just set the LD_PRELOAD environment variable, that's it! |
