[Tex/LaTex] Difficulties with Minted and UTF-8

mintedunicode

I'm trying to typeset Python programs with LaTeX and the Minted package. I'm under Ubuntu 15.10, with TeXlive installed from Ubuntu standard repositories. The python-pygment package is at version 2.0.1+dfsg-1. Compiling the code below :

\documentclass[11pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[francais]{babel}
\usepackage{minted}
% \setminted{encoding=utf-8}

\begin{document}
On importe toute la librairie Tkinter (attention, cette écriture ne fonctionne qu'en Python 3)
\begin{minted}{python}
from tkinter import *

# Creation de la fenetre de base de l'application
f=Tk()
# On lui donne un nom
f.title("Découverte de Tkinter")
\end{minted}

\end{document}

ends up with the following error :

! Package inputenc Error: Unicode char \u8:�co not set up for use with LaTeX. 
See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
...                                              
l.7 ...dq{}D�couverte de Tkinter\PYZdq{}}\PY{p}{)}

If I change the « é » in the string into a simple « e », it compiles silently. I've read somewhere it could be useful to set the encoding or outencoding parameter, but I get another error :

(./Python-Tkinter.w18)))/usr/bin/pygmentize
! Undefined control sequence.
<recently read> \setminted 
l.7 \setminted
              {encoding=utf-8}
?

I checked the /usr/share/texlive/texmf-dist/tex/latex/minted/minted.sty file (which is at version 2015/01/31 v2.0) :

user@machine:/usr/share/texlive/texmf-dist/tex/latex/minted# cat minted.sty | grep -E 'encoding|setminted'
    \ifx\encodingdefault\upquote@OTone
\minted@def@optcl{encoding}{-P encoding}{#1}
\minted@def@optcl{outencoding}{-P outencoding}{#1}
\newcommand{\minted@encoding}{\minted@get@opt{encoding}{UTF8}}
          %Need a version of open() that supports encoding under Python 2
            f = open(\"}#1\detokenize{\", \"r\", encoding=\"}\minted@encoding\detokenize{\");
            f = open(\"}\minted@outputdir\jobname.pyg\detokenize{\", \"w\", encoding=\"}\minted@encoding\detokenize{\");
        %Need a version of open() that supports encoding under Python 2
          f = open(\"}#1\detokenize{\", \"r\", encoding=\"}\minted@encoding\detokenize{\");
          f = open(\"}\minted@outputdir\jobname.pyg\detokenize{\", \"w\", encoding=\"}\minted@encoding\detokenize{\");
\newcommand{\setminted}[2][]{%
\newcommand{\setmintedinline}[2][]{%
\setmintedinline[php]{startinline=true}
\newcommand{\usemintedstyle}[2][]{\setminted[#1]{style=#2}}
    \setminted{style=default}%

Following an advice, here is the output from command line compilation with the \listfiles command :

So everything seems OK. I'm stuck. It would be great if someone had an idea. Thanks.

I was able to solve that (same) problem by using the lualatex-command instead of pdflatex for compiling. LuaLatex is Unicode-capable, so you (just) have to take care of two things in your TeX-file(s):

  • comment out the line where you import/configure the inputenc-Package:

    %\RequirePackage[utf8]{inputenc}

  • rebuild the whole document/project (for example in TexStudio there are two Buttons: "rebuild & view" and "compile". Just compiling e.g. wouldn't create a new Table of Contents , so lualatex would use the old *.toc-file - and could run into encoding errors there.)
