Only very new fonts contain proper Unicode glyph names since the full
Math extension has been only recently added to Unicode.  I thus
suspect that all those fonts have just a symbol cmap (and a second
cmap for Apple).

Well, if this is a symbol font it looks correct.  Windows, for
example, maps the character codes 0x00-0xFF of the symbol font
to positions 0xF000 to 0xF0FF.
