Upper/lowercase regex matching in unicode

[Jason Stitt]

What's the best way to match uppercase or lowercase characters with a
regular expression in a unicode-aware way? Obviously [A-Z] and [a-z]
aren't going to cut it. I thought there were character classes of the
form ::upper:: or similar syntax, but can't find them in the docs.
Maybe I'm getting it mixed up with Perl regexen.

The upper() and lower() methods do work on accented characters in a
unicode string, so there has to be some recognition of unicode case
in there somewhere.

Thanks,

Jason
