Like what the title says, if I use

\documentclass{article}
\usepackage{fontspec}
\usepackage{siunitx}

\begin{document}
\SI{5}{\um}
\end{document}

I would end up with 5µm. But changing \usepackage{fontspec} to \usepackage{mathspec} would result in it becoming 5m. What's happening? I was under the impression that mathspec is basically fontspec with support for math. Also, moving \usepackage{siunitx} before mathspec does not fix this.

  • As mentioned in the duplicate, add \sisetup{math-micro=\text{µ},text-micro=µ} after loading siunitx when you are using mathspec. – Henri Menke Apr 24 '18 at 00:16

    As far as I recall mathspec does not use unicode-math – JBantje Apr 24 '18 at 00:17
  • @HenriMenke That fixed the problem, thanks! But what about other symbols like Ω (has same problem with the micro-symbol)? I tried using math-omega=\text{Ω}, text-omega=Ω but it didn't work as I thought it should.

    Edit: changing it to math-ohm=\text{Ω}, text-ohm=Ω worked.
