You are right, for what I originally proposed. It would be like the current situation with case folding, that you can't paste in a search string with capital letters and search for it in a case-independent way. However, in the case of case folding, we solve that by downcasing text when pasting it into search strings. We could de-accent strings too when pasting them. -- Dr Richard Stallman President, Free Software Foundation (gnu.org, fsf.org) Internet Hall-of-Famer (internethalloffame.org) Skype: No way!
