But utf-8 hasn't been moved first, so this isn't a problem?

I agree it would be useful to be able to configure different loading
and saving time preferences.  Then I would be able to specify that
emacs should try to save data as ascii first, then latin-1, then
latin-9 and then UTF-8, then give up and ask.  On loading, I'd want it
to try latin-9 instead of latin-1 though.  In non-UTF-8 locales, I
think this behaviour is what many europeans would want.

Yup.
