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.")
