If you ever wondered when accents appeared in french... l'Académie française used the accents for the first time in 1740 with the 3rd edition of the dictionary:
L'Académie s'eſt donc vûe contrainte à faire dans cette nouvelle Edition, à ſon orthographe, pluſieurs changemens qu'elle n'avoit point jugé à propos d'adopter, lorſqu'elle donna l'Edition précédente.
Letters J and V were introduced a 22 years before in 1718 with the 2nd edition of the dictionary in order to clarify the pronunciation of words that were respectively composed with letters I and U.
Long s -- i.e. the glyph ſ -- disappeared from french in 1780 and was replaced by the s.
All this occurred only 250 years from now.
