I have plenty of reproaches for them too!  Thanks, I meant to conjure up 
that box.
I'm thinking of this as the _last_ step before sending a windowized 
pathname to the OS -- encode any of the char's shown except the 
PATH-SEP.  Actually, both slashes are verboten.  Coming back the other 
way I'd be tempted to be more permissive and try decoding any %XY | X in 
{0..9+A..F), Y in (0..9+A..F) but that may be an evil temptation. 
 Reversing only what we ourselves do is far safer.
