[Tex/LaTex] Issue with special characters in Python code

Question

I am trying to insert a Python code into a LaTeX document. The Python code (an example) is the following and contains many special characters (>, <, °):

valeur = input('Veuillez entrer une valeur numérique ° : ')

if '.' in valeur
    print('Hourra')

        if x<0 or x>10:

Here is a MWE:

\documentclass{article}

\usepackage[latin1]{inputenc} 
\usepackage[T1]{fontenc} 
\usepackage[francais]{babel} 

\usepackage{fancyvrb}

\begin{document}

\inputencoding{utf8}
\begin{otherlanguage*}{english}
\VerbatimInput[frame=single, numbers=left, numbersep=2pt]{test.py}
\end{otherlanguage*}
\inputencoding{latin1}

\end{document}

Because of the special characters, I am getting this error:

How can I fix it?

This question is closely related to the post Issue with accents from Python source code but it is no duplicate since I was dealing with accents and now I am seemingly dealing with mathematical symbols used outside math mode…

The answer to Issue with accents from Python source code does not solve my current problem.

Answer 1

You have to declare that you want to use UTF-8. For the degree symbol you also need textcomp.

\documentclass{article}

\usepackage[T1]{fontenc} 
\usepackage[utf8,latin1]{inputenc}  % last one is default
\usepackage[english,francais]{babel}
\usepackage{textcomp}

\usepackage{fancyvrb}

\begin{document}

\inputencoding{utf8}
\begin{otherlanguage*}{english}
\VerbatimInput[frame=single, numbers=left, numbersep=2pt]{test.py}
\end{otherlanguage*}
\inputencoding{latin1}

\end{document}

Why not using UTF-8 also for the other files?
