This is my minimum example
\documentclass[a4paper, 10pt]{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}
loads = {'-g·M·e·(Σsines),'; 'wind-like·half-sine,'};
\end{lstlisting}
\end{document}
%%% Local Variables:
%%% TeX-engine: xetex
%%% End:
and here it is what I get, using XeLaTeX on Debian Sid
Please notice the position of "Σ" with respect to "(" in the source and in the figure.
My question is, what is going on?
