  There is nothing in OpenType about Unicode names.  FontBook -- I'm
guessing -- simply shows you the names for those glyphs that have a
Unicode code point.  There is a bijection between code points and names.

  Some glyphs don't have a Unicode code point.  Unicode encodes
characters, not glyphs, and in some cases the glyphs you see in a font
do not correspond to any character.  This is in particular the case for
those glyphs that you see in Latin Modern Math.

  These glyphs or part or glyphs can probably be mapped one-to-one to
font slots in the original lmex10, but that does not make them
