Hello,
I've been setting up org-entities-user with a few custom symbols, and
managed to get a few aliases for items already in org-entities, but i'm a
bit stuck on adding new items - specifically, the mathbb versions of Z and R
(the symbols for the sets of integers and reals).  I can't seem to find the
UTF-8, latin-1, or HTML encodings of these entities - and I'm not sure how
to input the utf-8 or latin-1 even if I do.  Does anyone know how to do
this?

Thanks,
Nathaniel Flath
