A bare uc will do the wrong thing for the first letter of a word in those languages that distinguish tc from uc. Titlecase is distinguished from other uppercase forms that are used after the inital letter, and so doesn't care whether the next character is uppercase or lowercase. It's simply wrongish to use uc on the first character in such a language. Larry
