To me normalization seems preferable over just skipping the text in all situations including math, and it's trivial to do, so I think makes for a sensible default. Certainly they could then start adding special cases, reading out symbols intended for mathematical use like T-H-I-S (though, mathematical expressions often still have words). I'm not sure about "five unsupported characters omitted". Would probably need feedback from someone who actually uses a screen reader to be sure, but I feel that's less useful than normalization. Maybe a tone/voice alteration to indicate this? (playing with narrator, it does already change voice for control information)
