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. - - Konstantin Chuguev - <Konstantin.Chuguev@dante.org.uk> - November 2000. |
