Some of those are available through AltGr also.

and ¬, ↑, ×, etc. (and many more would be useful, e.g. to create your
own operators); I wonder if some Unicode character classes would be
useful as a filter here, or would it have to be manual?  Maybe have a
pragmat allowing extra Unicode characters?

+1 on that

I would love that too, although it might be useful to allow the user to
restrict (e.g. through pragmats, or on the command line, etc.) what
scripts (=subsets of Unicode) are allowed (to avoid various security
attacks with hidden/similar characters & such).
