My vote is against the patch because the nodef glyph will often be just 
blank space which is certainly worse than â–’.
If conhost does not provide a reasonable way to enquire 0xFFFD 
availability it's conhost's fault, not cygwin's so why should cygwin 
implement a bad compromise. If conhost ever improves, cygwin can adapt.
