Tatar language
There have been two Arabic alphabets used to write Tatar: İske imlâ and Yaña imlâ. İske imlâ is the older of the two and was used until 1920, when it was changed to become Yaña imlâ and remained in use until it was replaced by the Latin Yañalif alphabet. However, Tatars in China still use İske imlâ.
