This is exactly what I have to avoid. I know about all of above
mentionned but I'd like not to have to type `C-x RET l' sequence each
time when I open Latin-2 encoded file in order to be able to edit it.
I'd like to have files let know emacs to change language environment
to Latin-2 each time when opened.

Thanks.
