I am trying to highlight text that includes quantities using the siunitx package. Just as when highlighting other commands like \cite, they have to be enclosed in extra brackets. But a problem occurs when using binary units (\bit, \byte, \kibi\byte) which give an Undefined control sequence error. Other units like microseconds or megahertz are highlighted with no problem.
I leave a MWE. Appreciate any help I can get.
\documentclass{article}
\usepackage{color}
\usepackage{soul}
\usepackage{siunitx}
\sisetup{
binary-units = true,
}
\begin{document}
% These are OK
\hl{{\SI{32}{\MHz}}}
\hl{{\SI{32}{\us}}}
\SI{32}{\bit}
\SI{32}{\byte}
\SI{32}{\kibi\byte}
% These give errors
\hl{{\SI{32}{\bit}}}
\hl{{\SI{32}{\byte}}}
\hl{{\SI{32}{\kibi\byte}}}
\end{document}
