That is the reason for my question if the font fallback mechanism can
work for math fonts also (as it does for, e.g., using different fonts
for arabic and english). That will be much easier than building a
virtual font.

Yes, but those are not necessarily needed.

(in fact, a virtual font has to be built, so it's then a wrapper around a 
similar vf builder as we already have; one option is to extend the current 
one with ranges)


Just having a basic fallback mechanism will be better than having no 
fallback. For example Euler has no blackboard black, is missing some 
arrows (not extensible ones, just regular arrows) and common symbols.

The simplefonts module is written on top of the typescript mechanism
and there is nothing available at this level which can be used by the
module. When you use the \setmathfont command simplefonts loads only
one of the predefined typescripts.

I too would like to use Neo Euler for math but need some of the missing 
glyphs/symbols, like \angle and \triangle. What would the typescript look like 
to provide fallback to font for the symbols?
