Is there a way (MkIV) to set math to use upright symbols globally, for
Latin and Greek (I'm working on an OpenType math font that has no
italics).

Another slightly related issue, is it possible to get some visual
indication of missing glyphs, something like using .notdef char instead
of just leaving it blank.

Regards,
 Khaled
