tcolorbox for latex code with texlive 2023

Question

I'm sorry for my MWE too big. However I don't know how to make it smaller in this case. I want to use tcolorbox to frame latex code. Unless I'm mistaken this code worked under the texlive 2017 distribution. Now with Ubuntu 24.04LTS and texlive 2023 I have a slight typo that appears. here is the first mwe to make a box with title

\documentclass{minimal}
\usepackage[most]{tcolorbox}

\tikzset{coltria/.style={fill=red!15!white}}

this time the beginning of the text inside the box is eaten the word section is missing. Can you enlighten me on these 2 anomalies? I'm almost there, because it produces almost my 2 boxes. note: I am forced to compile in lualatex in my project for other reasons external to my question could you help me to understand what is about?

Answer 1

To begin with, \red is undefined and produces an error also with TL 2017. If I define it by

\newcommand{\red}[1]{\textcolor{red}{#1}}

the file compiles, but you lose all accented characters. With TL 2017 I get

which is obviously unacceptable. If I compile with TL 2023, I get

! LaTeX Error: Invalid UTF-8 byte sequence (�\lst@EC�).

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.1         \section{Installation sur système
                                               Linux}

which makes me think that your file is coded as Latin-1. Indeed, if I convert your text in a Latin-1 encoded document (StackExchange uses UTF-8) and add

\usepackage[latin1]{inputenc}

the run succeed.

However, you should go away from Latin-1 (and adopt UTF-8). There are still problems with listing and extended character sets, but there are several posts on the site to fix them.

Or switch to minted.
