I have a problem when trying to use the \ohm unit from the siunitx package when the detect-all option in the siunitx package is enabled, and the charter package is also used.

When detect-all is enabled and the charter package is used, the \ohm symbol will not show correctly (shows as a black box instead).

Miniumum working example (MWE) below:

\documentclass{article}

\usepackage{charter}
\usepackage{siunitx}

\begin{document}

This works: \SI{10}{\milli\ohm}.

\sisetup{detect-all,}
Now this does not work:  \SI{10}{\milli\ohm}.

\end{document}

You may have a look at this great answer. My proposal direclty comes from there

Basically the ohm symbol is not provided by the charter package, so you have to provide it another way

\documentclass{article}
\usepackage{siunitx}
\usepackage{arev}
\renewcommand{\rmdefault}{mdbch}

\begin{document}

This works: \SI{10}{\milli\ohm}.

\sisetup{detect-all,}
Now this does not work:  \SI{10}{\milli\ohm}.

\end{document}

  • Thank you for that. Your solution worked for my MWE, but gave errors when used in my larger document, probably due to inconsistencies with other packages. I'll try and find out what, and will update here if I do.

    In the meantime, as an alternative solution, I've moved from using the charter package to the XCharter package instead, which provides support for Greek letters.
