New in 1.18:
* Many more transliterations.
* GB18030 is now an alias for GB18030:2005. A new converter for GB18030:2022
  is added. Since this encoding merely cleans up a few private-use-area
  mappings, you can continue to use the GB18030 converter, for backward
  compatibility. Its Unicode to GB18030 conversion direction has been
  enhanced, to help transitioning away from PUA code points.
* When converting from/to an EBCDIC encoding, a non-standard way of
  converting newlines can be requested
    - at the C level, by calling iconvctl with argument ICONV_SET_FROM_SURFACE
      or ICONV_SET_TO_SURFACE, or
    - from the iconv program, by setting the environment variable
      ICONV_EBCDIC_ZOS_UNIX to a non-empty value.
* Special support for z/OS: The iconv program adds a charset metadata tag to
  its output file. (Contributed by Mike Fulton.)

New in 1.17:
* The libiconv library is now licensed under the LGPL version 2.1, instead of
  the LGPL version 2.0. The iconv program continues to be licensed under GPL
  version 3.
* Added converters for many single-byte EBCDIC encodings:
  IBM-{037,273,277,278,280,282,284,285,297,423,424,425,500,838,870,871,875},
  IBM-{880,905,924,1025,1026,1047,1097,1112,1122,1123,1130,1132,1137,1140},
  IBM-{1141,1142,1143,1144,1145,1146,1147,1148,1149,1153,1154,1155,1156,1157},
  IBM-{1158,1160,1164,1165,1166,4971,12712,16804}.
  They are available through the configure option '--enable-extra-encodings'.

New in 1.16:
* The preloadable library has been removed.

New in 1.15:
* The UTF-8 converter now rejects surrogates and out-of-range code points.
* Added ISO-2022-JP-MS converter.
* Updated the CP1255 converter to map one more character.
* The functions now support strings longer than 2 GB.

New in 1.14:
* The 'iconv' program now produces its output as soon as it can. It no longer
  unnecessarily waits for more input.
* Updated the GB18030 converter to map 25 characters to code points that have
  been to Unicode since 2000, rather than to code points in the Private Use
  Area.
* Updated the BIG5-HKSCS converter. The old BIG5-HKSCS converter is renamed to
  BIG5-HKSCS:2004. A new converter BIG5-HKSCS:2008 is added. BIG5-HKSCS is now
  an alias for BIG5-HKSCS:2008.
* Fixed a bug in the conversion to wchar_t.
* Fixed a small bug in the CP1258 converter.

New in 1.13:
* The library and the iconv program now understand platform dependent aliases,
  for better compatibility with the platform's own iconv_open function.
  Examples: "646" on Solaris, "iso88591" on HP-UX, "IBM-1252" on AIX.
* For stateful encodings, when the input ends with a shift sequence followed
  by invalid input, the iconv function now increments the input pointer past
  the shift sequence before returning (size_t)(-1) with errno = EILSEQ. This
  is also like GNU libc's iconv() behaves.
* The library exports a new function iconv_open_into() that stores the
  conversion descriptor in pre-allocated memory, rather than allocating fresh
  memory for it.
* Added CP1131 converter.

New in 1.12:
* The iconv program is now licensed under the GPL version 3, instead of the
  GPL version 2. The libiconv library continues to be licensed under LGPL.
* Added RK1048 converter.
* On AIX, an existing system libiconv no longer causes setlocale() to fail.
* Upgraded EUC-KR, JOHAB to include the Korean postal code sign.

New in 1.11:
* The iconv program has new options --unicode-subst, --byte-subst,
  --widechar-subst that allow to specify substitutions for characters that
  cannot be converted.
* The iconv program now understands long options:
    long option    equivalent to
    --from-code    -f
    --to-code      -t
    --list         -l
    --silent       -s
* The CP936 converter is now different from the GBK converter: it has changed
  to include the Euro sign and private area characters. CP936 is no longer an
  alias of GBK.
* Updated GB18030 converter to include all private area characters.
* Updated CP950 converter to include the Euro sign and private area characters.
* Updated CP949 converter to include private area characters.
* Updated the BIG5-HKSCS converter. The old BIG5-HKSCS converter is renamed to
  BIG5-HKSCS:1999 and updated to Unicode 4. New converters BIG5-HKSCS:2001 and
  BIG5-HKSCS:2004 are added. BIG5-HKSCS is now an alias for BIG5-HKSCS:2004.
* Added a few irreversible mappings to the CP932 converter.
* Tidy up the list of symbols exported from libiconv (assumes gcc >= 4.0).

New in 1.10:
* Added ISO-8859-11 converter.
* Updated the ISO-8859-7 converter.
* Added ATARIST converter, available through --enable-extra-encodings.

  --enable-extra-encodings.

  preloadable_libiconv.so.
