More likely Richard ~ along with virtually all the fellows who went to Jerusalem ~ spoke GALLO and not really French. There were NUMEROUS Gallo dialects throughout what we today call France, Belgium, Luxembourg, Germany ~ and standard French as spoken in the Ile de France (Paris and environs) was not all that developed.
Spain limped along with several languages, maybe 8 ~ Ladino, Arabic, Berber, Galician, Latin, Basque, Gallo, Cornwall, and several others.
