You can use CTFontManagerCreateFontDescriptorsFromURL() and then, for each 
descriptor, CTFontDescriptorCopyAttribute() with kCTFontDisplayNameAttribute.

Keep in mind that you may get multiple descriptors because a font file may 
include multiple fonts.  Consequently, there may be multiple display names.
