[XeTeX] Hyperref problem

[jropers@freesurf.fr]

In the process of making a short minimal example, I discovered that it 
works sometimes, and sometimes not.

Here it does not work in a big document where the sections were :

\section {étude }
\section{Les sujets devaient être âgées }
\section{Plusieurs échantillons}

the content of the .out file :
\BOOKMARK [1][-]{section.1}{\376\377\000é\000t\000u\000d\000e\000\040}{}
\BOOKMARK 
[1][-]{section.2}{\376\377\000L\000e\000s\000\040\000s\000u\000j\000e\000t\000s\000\040\000d\000e\000v\000a\000i\000e\000n\000t\000\040\000ê\000t\000r\000e\000\040\000â\000g\000é\000e\000s\000\040}{}
\BOOKMARK 
[1][-]{section.3}{\376\377\000P\000l\000u\000s\000i\000e\000u\000r\000s\000\040\000é\000c\000h\000a\000n\000t\000i\000l\000l\000o\000n\000s}{}


I will try later to reproduce the problem in a short example if I can.

Jacques.
