The recode reference manual

The recode reference manual

This recoding library converts files between various coded character sets and surface encodings. When this cannot be achieved exactly, it may get rid of the offending characters or fall back on approximations. The library recognises or produces more than 300 different character sets and is able to convert files between almost any pair. Most RFC 1345 character sets, and all libiconv character sets, are supported. The recode program is a handy front-end to the library.

The current recode release is 3.6.
