Use text font for punctuations in xelatex with unicode-math

Question

Suppose I have the following declarations in the preamble

\usepackage[utf8]{inputenc}
\usepackage{unicode-math}

\setmathfont{My Best Math Font}
\setmainfont{My Best Font}

and then some texts like so in the document:

$X, Y$ vs. $X$, $Y$

the commas within math and non-math environments will be different.

Is there anyway to make the math environment to use My Best Font for punctuations?

Thanks!

Answer 1

You can use the range option to exchange chars.

\documentclass{article}
\usepackage{unicode-math}

\setmathfont{Fira Math}
\setmainfont{TeX Gyre Termes}
\begin{document}

$X, Y $ X, Y

%should go in the preamble, in the body only for the example 
\setmathfont[range={44}]{TeX Gyre Termes}
\setmathfont[range=\int]{Fira Math}

$X, Y $ X, Y

\end{document}
