Unlike Tolkien and perhaps the Game of Thrones TV show (Dothraki, anyone?), Blizzard doesn't create complete languages, as far as I know.

They used to answer spoken fictional language lore questions on Twitter and their now extremely rare Ask Creative Development Q&A's, but that all seems to have withered.

For the most part they have never given broad info on written fictional language glyphs.

Your best bet is to hit some of the lore related devs on Twitter or ask on the official forums. Outside of that, you're probably out of luck.
