ICONV - Charset Conversion Library. Version 2.0
	-----------------------------------------------

This distribution provides:
	* the library (libiconv.a and .so) for conversion between
	  various charsets (character encoding schemes);
	* and the command line utility (iconv), providing
	  conversion of a file, standard input or its argument
	  line from one charset to another;
	* a set of coded character set tables (binary files) and
	  character encoding schemes (dynamically loaded modules)
	  for use by the library;
	* a utility for creating character set tables from Unicode
	  conversion tables and RFC1345-style charset descriptions.

Syntax of the library functions (iconv_open, iconv, iconv_close)
and the utility is described in the man pages.

Features of the library:
- Coded character set (CCS) tables are binary files containing
  pairs of tables for converting characters from some charset to
  Unicode (UCS-2 in host byte order) and vice versa. There are 4
  types of tables supported in iconv-2.0: for 7-bit, 8-bit, 14-bit
  and 16-bit charsets. The library uses memory mapping (in
  read-only mode) to access the table data.
- Character encoding schemes (CES) are small sets of C structures
  and functions. The functions implement virtual methods for
  converting a sequence of characters in some charset to a Unicode
  character (UCS-4 in host byte order). Each encoding scheme is
  located in a separate C file and can be compiled to a dynamically
  loaded shared module.
- A universal CES for all table driven charsets is compiled into
  the library and used for all CCS tables.
- Both CCS tables and CES C code can be built into the library by
  specifying the corresponding charset name in the
  ICONV_BUILTIN_CHARSETS make variable. By default us-ascii, utf-8
  and ucs-4-internal are built in (plus the CES for all CCS
  tables). All the CES modules are included to a static version of
  the library (libiconv.a).
- Multiple aliases for every charset are supported. All aliases are
  listed in the charset.aliases file(s). The library uses memory
  mapping to parse alias information and find a canonical name
  of a charset before looking it up in the internal list or
  external table or shared module. Alias information can also be
  compiled into the library (which is useful for compiled-in
  charsets ;-)
- ISO/IEC 10646 conformance of the internal representation of
  characters; conversion is done in two steps:
  (1) a sequence of zero or more bytes from input buffer coded in
      the source charset is converted to exactly one valid UCS-4
      character and
  (2) the UCS-4 character is converted to a sequence of zero or
      more bytes in the target charset to the output buffer.
  In the case when two charset names are found to be aliases
  of the same charset, conversion is done via a simplified
  converter by copying the data from the input buffer to the
  output one.
- Open module API: adding new modules is easy. API has only been
  documented via iconv.h file comments so far. A perl utility is
  provided for conversion of Unicode charset tables
  (http://www.unicode.org/Public/MAPPINGS/) and RFC1345-style
  charset tables into the CCS format recognized by the library.
- API conformance to Unix98 specification.
- BSD-style copyright.
