Question

i would like to know how can i put labels and names of sections and chapters using accents. I get errors when i try

\chapter{Conclusión}

\section{Other seccion name with áccent}
\label{algo}

Answer 1

we need a complete example with an error description ... This works:

\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\begin{document}

\chapter{Conclusión}
como se menciona en \ref{algo}.
\section{Other seccion name with áccent}\label{algo}

\end{document}
