are there codepoints in unicode that may be either upper-case or
lower-case, depending on the charset?  if so, then there's ambiguity
here, depending on the user's locale.  i suspect not, but languages
are strange beasts, and i don't know the answer.

There's a simple solution to that.

Just say that names consisting entirely of either ASCII-range uppercase letters or ASCII-range lowercase letters are reserved, and that names having either both of those or any of those plus non-ASCII letters are not reserved.

The only way I see this being a problem is if we forsee that we might want to have official names going out of the ASCII repertoire, which I would recommend we don't.
