## Description

Enca (Extremely Naive Charset Analyser) consists of two main components:

  * libenca, an encoding detection library.  It currently supports

    Belarusian, Bulgarian, Croatian, Czech, Estonian, Hungarian, Latvian,

    Lithuanian, Polish, Russian, Slovak, Slovene, Ukrainian, Chinese, and

    some multibyte encodings independently on language.  The API should be

    relatively stable (to be read as `it will either change only

    marginally, or very drastically').

  * enca, a command line frontend, integrating libenca and several

    charset conversion libraries and tools (GNU recode, UNIX98 iconv,

    perl Unicode::Map, cstocs).

## Installation

Enca should compile and work on every POSIX.1 compliant system with ISO C

compiler, and actually compiles on many noncompliant systems too (see below

for list dependencies).  If you have some of following additional tools,

Enca can use them as external converters:

* GNU recode and the associated recoding library

* Perl charset converters Unicode::Map8 or Unicode::Map

* cstocs, the famous Czech charset converter

Optional features:

* Compilation of GNU recode library interface is controlled by

  `--with-librecode[=DIR]`, `--without-librecode`

  configure parameters.  It is compiled in by default when found.

  Optionally, you can specify a DIR; librecode include files will be

  then searched in DIR/include and the library itself in DIR/lib.

* Compilation of UNIX98 iconv interface is controlled by

  `--with-libiconv=[DIR]`, `--without-libiconv`

  configure parameters.  It is compiled in by default when found

  and considered usable.  Optionally, you can specify a DIR; libiconv

  include files will be then searched in DIR/include and the library

  itself in DIR/lib.

* Compilation of interface to external converter programs is controlled by

  `--enable-external`, `--disable-external`

  configure parameters.  By default is is compiled in.

Don't even try to compile Enca on system not supporting following ISO C and

POSIX features:

* Function prototypes.

* Basic ISO C headers and functions declared there:

  - assert.h, ctype.h, math.h, stdarg.h, stdio.h, stdlib.h

  - any (working) one of string.h, strings.h, memory.h

  - unistd.h, sys/stat.h, sys/types.h

For the impatient: Run

    ./configure

    make

    make check

    make install

as usual.

## Bugs

Report problems at <https://github.com/nijel/enca/issues>. Some known bugs have

been collected in BUGS section of enca manual page.

## Hacking (with) Enca

Please see TODO for list of things that should be fixed and features to

be implemented and their priority and also for list of things that

definitely shouldn't be implemented.

The file DEVELOP.md describes what needs to be done to add a new

encoding or language to Enca.
