I received a message containing the question: "Not to nitpick though, but on p. 4 the one labeled "Hittite hieroglyphs," wouldn't they be in Luwian and not Hittite (Nesite)?"
These inscriptions were once commonly known as Hittite hieroglyphs, but the language they encode proved to be Luwian (a language related to Hittite) and nowadays the term Luwian hieroglyphs is used in English publications.

I do not know the answer, any takers?
