Re: upper() vs. lower()

I know that if you move towards unicode, you'll probably do better by going
to lowercase since I understand that there are more lowercase letters than
uppercase (for some odd reason!).  I think it's related to the fact that
some languages have multiple lowercase letters that will map to a single
uppercase letter, so there's great "distinct-ness" with lowercase.
