It is important to add a test. Your suggestion to use a working 
directory containing unicode characters is probably the best that can be 
done at this time.

Did you think any more about eliminating getNativePath? It should be 
possible to move this into 
src/windows/classes/java/lang/ProcessImpl.java and since the working 
directory is already normalized it should be simpler too.
