How to keep character encoding in text file...

[Marko Myllymaki]

I usually work with UTF-8 encoded files and my system is set up for 
UTF-8 (text may be in english, finnish, swedish, german, russian...)

However, sometimes I edit latin1 -encoded files and I would like to have 
the encoding automatically kept that way when saving files. Now it seems 
to change unwantedly to UTF-8 sometimes... I have to use iconv command 
line tool to change this...

So... if I load UTF-8 encoded file, emacs always saves it that way. If I 
open latin1-encoded file, it should keep it in the original encoding.

Maybe something to put in .emacs to achieve this...
