Hi, hope everyone's doing well!
Is it possible to setup math font so that all the basic ascii characters (i.e.
a..zA..Z0..9) glyphs are substituted with current serif (or sans) font. I tried
playing with fallback thing but it didn't got me anywhere!
e.g. $x$ will use the 'x' glyph from current serif italic font, and $\bf x$
will use the 'x' glyph from current serif bold font!
I would appreciate any suggestions and help!
Suppose we have all the required font files in the 'font' directory of the
working directory, and below is the minimal source code!

More like this (if you want decent math). Also, use a math font as base
that matches the fallbacks, also metric wise.
