You're right in that we really ought to fix everything.  However, I'm 
happy to just fix some of these things, even if it introduces some 
inconsistencies in the meantime.  We already have much of 
System.Directory working with Unicode FilePaths, so there are already 
inconsistencies here.

Thanks for reminding me that openFile is also broken.  It's easily 
fixed, so I'll look into that.
