This command finds ä, too, even if it is displayed without \ on
screen.  I presume it will also find a lot of other nonascii
characters.

Suppose you have a file which is mostly in the foo encoding, but
contains some bytes that are invalid in that encoding.  I think this
is the situation Dan is talking about.  He wants to find the invalid
bytes, IIUC.

Maybe it helps to try to save the buffer to a file, and let Emacs
complain about the character that couldn't be encoded using the
current coding system.  But I'm not sure if that does the trick,
though.
