If you don't know Enca, it 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.
Full list of changes for 1.15 release:
- Documentation improvement
- Development moved to GitHub
- Do not use deprecated autoconf macros
Still enca is in maintenance mode only and I have no intentions to write new features. However there is no limitation to other contributors :-).
