This sounds serious in theory, but I was unable to make emacs behave
unexpectedly in practice.  Do you have an example?

I tried opening a new file and typing åäö and saving it.  It was saved
(without query) as latin-1 with sv_SE, en_GB, en_US and C locales.
All are what I would expect, and is consistent with what I get for
emacs 21.3. (Of course, this is a western-centric test case, but I
don't know what non-western users expect so I can't really test
anything else.)

Note that iso-8-1 is still prefered over utf-8 with Kenichi's change.

Note also that mule-cmds.el seem to guess the appropriate charset for
most locales, so UTF-8 will never be prefered over the "locale
charset".  A jp_JP user will have a low priority for UTF-8.
