More accurately, if finds _any_ non-ASCII character. That's what it
is supposed to do.

Perhaps I don't understand the original request, but if I do, it is
very hard to do that (AFAIK) without knowing what--i.e. which
character sets--are you looking for. Recall that, once the file is
visited by a buffer, there are no bytes, just characters. What you
want is to find characters that don't belong to some set of
characters, without actually telling Emacs what are those ``good''
sets. This might be relatively easy if your buffer holds characters
from a single charset, but I doubt that Emacs users can be charged
with the burden of knowing about such technicalities.

It doesn't; see my other mail.
