I was recently looking for a good resource on what's included in the unicode
tables and what isn't.
This one was one of the best I could find: http://barzilai.org/math_sym.htm
But (repeating the previous posts), this doesn't cover all symbols necessary
to express mathematical (or for example chemical) formulas.
Especially when thinking about OAI, I'm really wondering if _any_ standards
or agreements apply ?
Does anyone know how they do this in "big" reference repositories ?
Maybe I was just unlucky after looking for a few references, but it doesn't
seem that these submissions in Arxiv include special symbols:
http://arxiv.org/abs/0811.1165
http://arxiv.org/abs/0811.0548
In any case, interesting topic and hope there are some good solutions out
there.
