If they are easy to type, this might be convenient. If they are hard, I think the existing default is better for handling case, and maybe for diacritics too. Meanwhile, there is also the issue of discoverability. If case-fold search required memorizing a special character, most users would not memorize it and would never use it. -- Dr Richard Stallman President, Free Software Foundation (gnu.org, fsf.org) Internet Hall-of-Famer (internethalloffame.org) Skype: No way!
