There are quiet some questions about getting accents like è into the lstlisting
environment. But I actually want to have a free floating accent. However, Latex always changes it to some other symbol so copy pasting the code will not work.
Here a MWE:
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}
`if`(...)
\end{lstlisting}
\end{document}
