AWB General Fixes adds DEFAULTSORT to [[Académie Royale de Philatélie]] as {{DEFAULTSORT:Académie Royale de Philatélie}}.
Not sure if it should add {{DEFAULTSORT:Academie Royale de Philatelie}} (with no accents) or not add anything at all, but adding a DEFAULTSORT with the exact page name is not necessary.
