Michail,

I'm afraid I don't have much time to spend on this, but I did give your
code a fast look.  Nice work!  I don't know if you realise, but your
patch probably fixes a performance issue too:

I think assuming UTF-8 is reasonable because VTK already assumes ASCII,
and UTF-8 is a superset of ASCII.

Have you tried running VTK's tests with your new code?  Do they all pass?

PS: I'm moving this discussion to the vtk-developers list only, instead
of both lists.
