open the file, then call set-buffer-file-coding-system, then type the encoding system you want. Type Tab to see a list of possible values.

this page might help:

• Emacs and Unicode Tips

you could also run a lisp program that changes all your files in a dir to utf-8 or any other encoding. you could do this in python or elisp.

For python, see:

• Converting a File's Encoding with Python

for elisp, see:

• Emacs Lisp Examples

look for the section to-unix-eol there.
You'll need to change the line

(set-buffer-file-coding-system 'unix)
(set-buffer-file-coding-system 'utf-8)

on linux, there's a command line tool iconv that does this as well. Java solution is also there linked in the python page above.
