Uhm, Latin2 _is_ a subset of UTF-8.

Any non-broken editor _has_ to use encoding B and only encoding B, at least
not without a very explicit user override. So it loads the file assuming it
uses encoding B (Latin2 in your case) and also saves it in that way.

Just do this: iconv -f utf-8 <po >tmp;$EDITOR tmp;iconv -t utf8 <tmp
It will use the local encoding when running the editor.

The only editor-agnostic way would be to change the locale, intercept all
input and output of the editor -- doable on tty, much harder in X, and a
very bad idea generally. Few editors can handle a different encoding for
on-disk files and their user interface, and they are not really supposed to
anyway. As it's unwise to mess with the user's locale, you can change only
the on-disk one, and this is the way to go.
HTH.
