I love typography at large: do you know that accents appeared in 1740 in french?
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.
