I just pushed another update to OSProcess for Cuis. I think that it
will address most concerns related to calling VM plugin primitives
with UTF8 strings.

The OSProcessPlugin was written with the expection that string
parameters would be simple byte strings, but they work equally
well if byte arrays are used instead of the byte strings. Thus
when I changed the primitive calls in the image (OSProcess) to
convert strings to ByteArray, we now get the expected results.

I expect that other things will need to be addressed in OSProcess
for Unicode, but this should at least be a good start.
