By the way Eric, UnicodeData.txt doesn't contain all the unicode

For the purposes of this thread -- filtering non-alphanumerics -- I believe UnicodeData.txt is sufficient.

OK :)

If you have evidence otherwise, please cite the specific files that would be needed.

No argument in this specific case. But now you've changed the case of the conversation.

The sentance I replied to, you were talking about a more general case. My Unicode upper casing code for example needed SpecialCasing.txt and UnicodeData.txt. This project of mine (UnicodeStuff.rb) can uppercase ß into SS, something RB can't do (as well as a few hundred other characters not mapped by RB). Mine does case operations around the same speed as RB, only it does more than RB does, it's closer to the Unicode standard. (Although I don't know Unicode well enough to say that it is exactly to the standard.)
