I've imported a MATLAB code in my document by using the \lstinputlisting environment but I have the following errors about the accented letters:

package inputenc error: invalid utf-8 byte sequence;
package inputenc error: invalid utf-8 byte "A0;
package inputenc error: invalid utf-8 byte "A8;
package inputenc error: invalid utf-8 byte "A9;

etc... How can I fix these errors?

This is the main.tex:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{xcolor}

\usepackage[hyper]{listings}

\renewcommand{\lstlistingname}{Listato}
\newcommand{\lstInCaption}[1]{\lstinline[basicstyle=\ttfamily\footnotesize]|#1|}

  • Make sure you’ve loaded an encoding that contains the accented letters you want. If you’re using LuaLaTeX or XeLaTeX, you can just \usepackage{fontspec} to use Unicode, and you’re fine. In PDFTeX, you probably want \usepackage[T1]{fontenc}.

  • If you’re using PDFTeX, also make sure you’ve saved your source file as UTF-8 in NFC form (that is, as precomposed characters). PDFTeX can’t handle combining accents. If it’s not in UTF-8, either save it as UTF-8 or load selinput to figure out the input encoding.

  • with pdflatex the best is to use the literate key to define replacements, see e.g. tex.stackexchange.com/q/214828/2388 Mar 28 at 19:47
  • Thanks to everyone for the asks. I work on an overleaf project online. I've modified my question by adding some packages that are listed in my doc_style file

I solved the problem with the package listingsutf8 and then by setting the encoding using \lstset{inputencoding=utf8/latin1}.
