On OS X, Cocoa and Carbon use Core Foundation, whose API does not have a
one-true-encoding internally. Follow the rather long URL for details:
I would vote for an API that not just hides the internal store, but allows
different internal stores to be used in a mostly compatible way.
However, There is a UniChar typedef on OS X which is the same unsigned 16 bit
integer as Java's JNI would use.
