Fonts & Character Sets ⇒ Accents in \label and \ref arguments

[Tititex]

Hi, I'd like to know how to include words with accents in \label{} and \ref{} arguments.


For example : \label{Molécules d'immunoglobulines)
\ref{Molécules d'immunoglobulines}


I've already succeeded giving file names with spaces and accents to the argument command \includegraphics{} thanks to the package grffile, but I can't find an easy way to do it with \label{} and \ref{} commands. Do you have any idea ?

Thanks.

It is in fact possible with unicode-aware engines like XeTeX and LuaTeX. But really, don't do it.

Code: Select all

% arara: xelatex
% arara: xelatex
\documentclass{article}
\begin{document}
\section{Heart}\label{♥}
Listen to your \ref{♥}
\end{document}

It is completely impossible with pdfTeX. Sorry. That engine has no clue that there is more than the 52 letters of the latin alphabet (and numbers and punctuation), or in other words: pdfTeX has no idea that there is more in the world than ascii.

Welcome to the forum!

As labels are only internally used, I would use shortcuts anyway, as long as I and somebody else reading the code can understand the key / label.

Nice to see a user writing French again. Friends and I think about starting a French LaTeX support forum. We set something first up on TeXnique.fr. Do you think it would be a good idea?
