I don't get any error messages, but the VM resopnds as if the -eventenc
parameter does not exist. Meaning that running...

/home/Bob/Desktop/Squeak-3.9-9/build/squeak -eventenc UTF-8
~/.npsqueak/SqueakPlugin.image

is identical to running...

/home/Bob/Desktop/Squeak-3.9-9/build/squeak -edsfrsdf UTF-8
~/.npsqueak/SqueakPlugin.image

I would agree... Another idea floating in the air is to use the xutf8*
set of functions...from what i know this set is going to be integrated
into the OLPC distribution too, so it may become handy...but...one step
at a time.

Yes, i could start the VM without the -eventenc parameter but i could
not enter any non-english chars...
