How about if we reverse the letters as well as issue a warning? That is,=20 instead of merely displaying "ces" for a reversed "sec", we also display=20 the individual characters reversed (so it would display like "=E2=86=84=C9= =98=C6=A8"). On=20 a graphical display we should be able to do that reasonably well, and=20 it'd be a strong visual cue.
