I think the point is that for toUpper etc to be properly Unicoded,
they can't simply look at a single character.  IIRC, there are some
characters that expand to two characters when the case is changed, and
then there's titlecase and so on.

toUpper etc. are AFAIK only implemented correctly for a small (but
IMHO probably the useful) subset of characters.

I must admit I haven't looked at HBC -- are these functions
implemented properly for codepoints >127?  Outside the ISO-8859-x
ranges?
