Internal Program Version:  Enca 1.13  (The HEADER-Files)

Enca detects the encoding of text files, on the basis of
knowledge of their language. It can also convert them to
other encodings, allowing you to recode files without
knowing their current encoding. It supports most of Central
and East European languages, and a few Unicode variants,
independently on language.
