unicode data - accessing codepoints > FFFF on narrow python builts

It's a bug. It should either raise an exception, or return the correct
result. If you know feel like submitting a bug report: please try to
come up with a patch instead.

See PEP 261. This is by design.

Just use a wide Unicode build instead.
