Mark,

If I understand you correctly, you want to be able to write text with
characters like the following:
<http://en.wikipedia.org/wiki/Unicode_Mathematical_Operators>

If so, you will be sad to know that VTK does not support Unicode.  Your
best bet is probably to render the characters you want as bitmaps, then
feed the bitmaps to VTK.
