Character encoding is a pain... If you find yourself wanting to change the encoding of a file, here is how to do it in emacs:
C-x RET f utf-8 RET
When you then save the file, it is written with the specified encoding. If you can't remember the exact name of the encoding type:
C-x RET f TAB
This will give you a list of all available encodings in the help buffer.
