Under the Apple menu, choose Aide. In various areas you will see that the accents are correct until actually selected.
For example:
in Sommaire, choose Base de donnees, and select Creation d'une requete (notice accents are correct here).
What appears on the top left of the ClarisWorks Aide window as a result is Creation d'une requete.
This is a known bug in the French version of ClarisWorks.
