Adobe solved this with CID-keyed fonts. Instead of naming every glyph, a CID-font uses a two-part system:
Instead of naming a glyph "A," the system gives it a numerical ID (a CID). This makes the file more efficient, but it also makes it harder for other programs to read if the font isn't "fully embedded" into the file. Why is it showing up as "F1 Normal"? Cid Font F1 Normal
