Dear Harry and Indologists,
If it is in the context of the "scripts" category, then W refers to "Newari" script. However, in a previous thread we already established that "Newari" (along with Nepalaksara, etc.) comprises a range of different scripts (Bhujimol, Pracalit, etc.).
I had a cheat sheet for abbreviations somewhere. I'll look for it and post it here unless someone gets to it before me.
Happy holidays.
Sincerely,
