latex interpretation of selected German and Latin as well as mathematics-physics characters via matlab-prettifier

Question

I want to append some matlab code to a tex document and I use the matlab-prettifier package for that. I updated my miktex installation yesterday and I am now forced to use the \UseRawInputEncoding code line. Everything works fine for the German and Latin symbols I have in my matlab code, except for the degree sign, which comes out as an r with an inverted hat above, regardless of whether I use the literate substitution approach or not. Any suggestions on how to solve this elegantly would be welcome.

Here is my MWE:

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[framed,numbered]{matlab-prettifier}
\usepackage{textcomp}


\UseRawInputEncoding

\begin{document}

\lstset{
  language=Matlab,
  style=Matlab-editor,
  basicstyle=\mlttfamily\footnotesize,
  literate=%
    {°}{\textdegree{}}1%
}

\lstinputlisting[]{matlab_code.m}

\end{document}

and my matlab_code.m file reads as:

% ----------------------------    
% Rö and Mé (T = 23°C)
var_1 = 10;

Obviously, I can write degree instead of ° in the matlab file and substitute that by \textdegree, but I would like to bring changes to the matlab code to a minimum and actually use the degree symbol, whose use comes much more naturally than that of the corresponding text. Is it possible to directly read in tex and via matlab-prettifier a ° symbol written on a matlab file, rather than "going around" by substituting the corresponding degree text by the actual symbol?

Answer 1

There's no coverage of UTF-8 by listings, unfortunately. But \UseRawInputEncoding is not the right tool.

\documentclass{article}

\usepackage[T1]{fontenc}
\usepackage[framed,numbered]{matlab-prettifier}

\begin{document}

\lstset{
  language=Matlab,
  style=Matlab-editor,
  basicstyle=\mlttfamily\footnotesize,
  literate=
    {°}{\textdegree{}}1
    {ö}{{\"o}}1
    {é}{{\'e}}1
}

\lstinputlisting[]{matlab_code.m}

\end{document}

For completeness, here's what I get with minted.

\documentclass{article}

\usepackage[T1]{fontenc}
%\usepackage[framed,numbered]{matlab-prettifier}
\usepackage{minted}

\begin{document}

\inputminted[frame=single,linenos]{matlab}{matlab_code.m}

\end{document}
