I read your answer to my post as an admission that STIXGeneral, which
covers actually all the usual 'text' blocks of the Unicode is not really
suitable for text? Is it really so? My naive perhaps perception was that
STIXGeneral was not just a 'Math' font but a complete font that was
expected to be used for both text and Math.

Why then bother about designing 'OldStyle' figures in XITS Math? My
understanding is that one uses them exclusively in the text -- not in the
Math mode. Or there is a provision somewhere in 'unicode-math' for them to
be used also in Math? (if there is one, I haven't found it)
