They allow it, but it's not really the Right Thing.  Lu is an artifact
of the general classification system, which doesn't allow something to
be both a symbol and a letter.  Alphabetic is far better, and it's what
should be exposed.

I'm not sure I like having so many multiple names for patterns, however.
Pick one and stick to it, I think.
