xspace doesn’t handle \,

Question

When using a macro ending with an \xspace followed by a small space \, xspace inserts an extra (normal) space.

\documentclass[parskip=half]{scrartcl}


\usepackage{xspace}
\newcommand{\USB}{USB\xspace}

\begin{document}
    \USB-Port (o.\,k.)

    Use \USB to \dots (o.\,k.)

    \USB\,A-Plug (too much space)
\end{document}

Would it be possible to fix this?

Answer 1

Use \xspaceaddexceptions{\,}. See section 1.1. of the xspace manual.

\documentclass[parskip=half]{scrartcl}

\usepackage{xspace}
\xspaceaddexceptions{\,}

\newcommand{\USB}{USB\xspace}

\begin{document}
    \USB-Port (o.\,k.)

    Use \USB to \dots (o.\,k.)

    \USB\,A-Plug (o.\,k., too)
\end{document}
