That was exactly the requirement: use greek and latin characters at the 
same time to display mathematical expressions

No, that does not double the memory usage. I have just inserted a 
Text.IsWide function to let a future
version of VBT.PaintText select whether it wants to use XDrawString16 or 
its eight bit counterpart.

Yes it is shipped with X11R4

upgrading to WideChar32 would AFAIK be a major effort, not a simple fix:
first you would have to upgrade the whole Trestle kit to X11R6
you would have to use the very heavy weight X11R6 XIM interface to make 
use of WideChar32
then you would finally have to change the internal representation of the 
Text type.

I do not consent. WideChar32 will come with the additional benefit of 
some additionally supported languages. That is all it would be good for.
If we ever upgraded to use XIM which will be a major effort as I have 
already tried to point out we can still consider WC32 though converting
between UTF-8 and UTF-16 is no big deal (I have an implementation which 
I could give you.).

i.e. X11R4 uses WC16
      X11R6-XIM uses WC32

I do not want to speak against WC32; Nonetheless
it basically depends on how much effort you are willing to invest.
