   The control sequences for `\alpha`, `\beta` etc are redefined here.
   The `\alpha` expands to the character with Unicode `"03B1`, this is a normal
   character $α$. You can type it directly in your editor if you know how
   to do this.

Example of using additional math font is in section 5.3 in the

You can combine more Unicode math fonts in single formula simply
by the `\addUmathfont` macro, see
