Treat the Unicode "Letter, Other" class as lowercase letters (#1103)
This is an arbitrary choice, but it's strictly more useful than the
current situation, where these characters cannot be used in
identifiers at all.

In Haskell' we may revisit this decision (it's on my list of things to
discuss), but for now this is an improvement for those using caseless
languages.
