Bash-4.2 changed the command-not-found message to attempt to make sure that
all the characters it displayed were printable, to catch weird characters
in filenames and prevent the display from messing up the terminal. That
code needed some more work to accommodate multibyte characters. Try the
attached patch and see if it fixes your problem; it's from the current
development sources.
