When I copy "ελληνική γλώσσα" from Firefox and paste  
this into Squeak under Linux (using OLPC image and VM), the first  
character is 16r3B5 which seems right (although, in my image it is  
displayed as "??????? ???????"). I can't copy a WideString out of  
Squeak, however.

And typing greek chars on the keyboard only works if running under  
Sugar. We have no better way to test if we actually have a new VM. I  
attached a CS that tries to do a better job - always use Unicode  
keyboard input, but fall back to MacRoman if the unicode char is 0.  
Let's see what Yoshiki thinks of this ...
