The FAR file manager, http://en.wikipedia.org/wiki/FAR_Manager does it
quite
reliably using statistics about the character frequency distribution.
The tables themselves are quite small (about 1 Kbyte); the 8-bit
encodings are language-dependent, the Unicode encodings are
autodetected in a more general way.

Here are the tables I have for Cyrillic:

I think there is a similar package in emacs, although its emphasis is
on language recognition rather then on the encoding.
