I seem to recall that there is an organization in France that is the worldwide canonical guardian of the French language. Or maybe it's just for France. But I do not remember its name.
In Canada, I believe that this is governed by the Quebec government's Charter of the French Language and that it designates "L’Office québécois de la langue française" as the arbiter of the French language in Quebec. Perhaps it cooperates or defers to its France counterpart; but I don't know that either.
What organization is the official guardian of the French language in France and/or worldwide?
