Literata has about 1700 glyphs and 1200 characters. (I don't count Unicode composites - it is a different story).

 I'm not an expert, but you can have glyphs that are not mapped to any character, or glyphs that are just a character's components (not Unicode composites, as you wrote, but internal components)

Have you seen any printed books using slab serif?
