I read about this issues in a Unicode forum before.

For example ß can be a greek letter and it does not match ss in that case. Or
a mathematic symbol which has no othercase at all... There are some complicated
cases in the arabian languages as well. As far as I know there is no nice way
to handle these cases, too many exceptions, and exceptions of exceptions...

At the moment we simply use the unicode othercase / type tables. They have an
acceptable library size increase and defines the common behaviour.
