I don't think they would be written in any known language. I'm not even sure there's a need to know the language the last dragonborn learned just from opening it. Both in the Main questline and in the Dawnguard questline.

As for other languages, I know the Dunmer at least have their own language or at least their own word. Considering every time I walk past one, they turn to say "Yes. Sera?"
