The present-day q was variously written as ⟨ch⟩, ⟨chi⟩, ⟨k⟩, ⟨ky⟩, ⟨kj⟩, k with dot (Leake 1814) k with overline (Reinhold 1855), k with apostrophe (Miklosich 1870), and ⟨ḱ⟩ (first used by Lepsius 1863). ⟨q⟩ was first used in Frashëri's Stamboll mix-alphabet in 1879 and also in the "Grammaire albanaise" of 1887. The present-day dh was originally written with a character similar to the Greek xi (ξ). This was doubled (ξξ) to write 'th'. These characters were used as late as 1895. Leake first used ⟨dh⟩ and ⟨th⟩ in 1814. dh was also written using the Greek letter delta (δ), while Alimi used ⟨đ⟩ and Frasheri used a ⟨d⟩ with a hook on the top stem of the letter. This letter was not usually differentiated from ⟨e⟩, but when it was, it was usually done by means of diacritics: ⟨ė⟩ (Bogdani 1685, da Lecce 1716 and Kristoforidis 1872), ⟨e̊⟩ (Lepsius 1863), ⟨ẹ̄⟩ (Miklosich 1870) or by new letters ⟨ö⟩ (Reinhold 1855), ⟨υ⟩ (Rada 1866), ⟨œ⟩ (Dozon 1878), ⟨ε⟩ (Meyer 1888 and 1891, note Frasheri used ⟨ε⟩ for ⟨e⟩, and ⟨e⟩ to write ⟨ë⟩; the revision of 1908 swapped these letters) and ⟨ə⟩ (Alimi). Rada first used ⟨ë⟩ in 1870. These two sounds were not usually differentiated. They were variously written as ⟨g⟩, ⟨gh⟩ and ⟨ghi⟩.
