Better: you can easily search incrementally for non-ascii chars, starting with
Emacs 22, like this: C-M-s [^[:ascii:]]
I just filed an Emacs bug (#7809) to get this info added to the Emacs manual.
It was added to the Elisp manual (node `Regexp Special') in Emacs 23, but
apparently it wasn't considered useful info for users. ;-) (Probably just an
oversight, actually.)

If you use Icicles, you can also see and search for all
sequences of non-ascii chars this way: C-` [^[:ascii]]+
`S-TAB' to see hits, `C-next' to visit them, etc.

When the set of hits is thus those defined by [^[:ascii]]+, you can type any
string using a subset of those chars (i.e., one or more particular non-ascii
chars) to narrow the hits, then visit any of those, and optionally replace any
or all of them with alternatives.
