And file-in the TrueType related stuff.
Load your favourite unicode TrueType Font...and you are there...well
almost..we will have to fix some things from this point on...

(This goes to everyone...)
What do you say we start maintaining a Unicode version of the Squeak VM for
Windows and Unix...
It is something that many countries desire as opposed by Subbu...
Also with the upcoming of OLPC with eToys inside it is something that will
be mandatory in the very near future...
It doesn't worth it for everyone trying to find glitches anf fixes for
himself...
What do you say?

Christos.
