Internal Program Version: recode  3.7.15

The Recode library converts files between character sets and
usages. It recognises or produces over 200 different character
sets (or about 300 if combined with an iconv library) and
transliterates files between almost any pair. When exact
transliteration are not possible, it gets rid of offending
characters or falls back on approximations. The recode program
is a handy front-end to the library.
