Now if MS SfM and Cygwin had both registered with U/CSUR, they would not be 
fighting over Unicode code points, although it looks like there is a lot of 
competition for the code points! ;^>

Would it make more sense to add custom file name character filters into some 
utility, such as unix2dos/mac2unix, cygpath, or some other, and add (Cyg)win, or 
create such a utility, so those could be added to processes?
