No.  Lower-casing and title-casing work fine (unless there is a
problem with Khutsuri). One of the problems is that upper-casing has
been used where title-casing should have been used.

Upper-casing is where the problem is.  The long-term question is
whether it should be split into upper-casing that has no effect on
Georgian and emphatic-casing that also affects Georgian. Obviously
these functions are locale sensitive - remember Turkish.
