Description:

Enca is an Extremely Naive Charset Analyser. It detects character set and
encoding of text files and can also convert them to other encodings using
either a built-in converter or external libraries and tools like libiconv,
librecode, or cstocs.

Currently, it has support for Belarussian, Bulgarian, Croatian, Czech,
Estonian, Latvian, Lithuanian, Polish, Russian, Slovak, Slovene, and
Ukrainian and some multibyte encodings (mostly variants of Unicode)
independently on the language.

Install Enca if you need to cope with text files of dubious origin
and unknown encoding and convert them to some reasonable encoding.
