InterpreterProxy>>ioFilename:fromString:ofLength:resolveAliases:?

[John M McIntosh]

I believe fname here and length is technically the smalltalk object,  
and it's length. If you copy over from the fname it may not have
a terminating 0x00.

buf[length] = 0x00

Also if you run the image as UTF-8 would copying the file name  
directly and assume you've get a file name that is usable by Windows,  
is that correct?
