But that doesn't help always: 

Assume you have a buffer in latin-1 encoding which contains umlauts, 
add a umlaut in latin-9 and press C-x C-f. Then emacs complains that it
cannot safely save the buffer without showing the offending characters. In
fact it can't because it doesn't know if the latin-1 umlaut is wrong or the
latin-9 umlaut; and both look the same in the buffer :-(
