+            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, GB18030:2022, 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},
+            IBM-{1144,1145,1146,1147,1148,1149,1153,1154,1155,1156,1157,1158},
+            IBM-{1165,1166,4971}
+        Semitic languages
+            IBM-{424,425,12712,16804}
+        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.
