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!
