[BRLTTY] Unicode mathematical symbols

[Sébastien Hinderer]

Dear all,

I'm wondering whether work has already been done in brltty to represent
Unicode mathematical symbols in braille. I think not.
Are there already widely accepted braille representations for such
symbols?
If not, shouldn't we try to come up with something?
Is it allowed for a Unicode symbol to be represented by moe than one
baille character and ifos, is it suitable to do that for mathematical
symbols?

Thanks!
Sébastien.
