I just tried the latest OSProcess on an older Cuis image, #4738, from 
August 2021. This was before UnicodeString became the default String 
class. At that time, it was the old String from Squeak. OSProcess works 
OK there. I'm pretty sure the problem are the instances of 
UnicodeString, that should be converted to, maybe, bytearrays that end 
with a zero byte.

Dave, can you take a look?

Thanks,
