Another problematic glyph name in the the OT1 mapping is 'ringfitted',
which doesn't exist in the Adobe Glyph List.  It should be replaced
with 'ring'.

Looking into the TeXLive repository, it's funny that none of the
various Computer Modern font incarnations in any font format have a
glyph called 'ringfitted'.  Only 'mathdesign' and 'newtxsf' Type1
fonts have them, and I guess that its author could easily recreate
them with updated mappings.
