If I do understand Nicola correctly we should just send a NSString from 
the front end to the back end. Which is probably the most easiest 
solution. As we will only do this from the NSStringDrawing code and 
advise all users to use that instead we could replace this later on, 
with out much trouble. So as for a short time solution we add this extra 
method on NSGraphicsContext, whichs default implementation is just the 
conversion to the font encoding currently done by the drawiong code.
And everybody that wants to see real 16 Bit characters just slots it a 
better implementaiton of XGFont (I will polish the standard one up a bit 
to support this as well)
This will be a derivation from a pure PostScript drawing interface (as 
an exchange I will postbone the Bezier path extension), but I promise to 
make sure it works for the xdps backend and for PS printing.
