Writing Problems and to be abolished the Uyghur alphabet in Iran With a look at the thesis "Uyghur writing etiquette from the 9th century AH"

The Uyghur script was used in Iran from the 7th to the 9th century in governmental correspondence, writing manuscripts and documents. Despite its importance for the rulers and court system, limited and often precious copies of this script have been left. But, this fact that: why there are few written works in Uyghur script, or what could be the reasons for its early decline, has not been studied yet. In this research, by using the method of historical analysis and cognitive text, the Uyghur alphabet and its writing style and the problems of writing with it are discussed. While introducing a unique historical thesis, it is assumed that the incompleteness of the Uyghur alphabet, as it does not have an equivalent for some letters of the alphabet and is forced to use the same symbol for several letters of the Persian/Arabic alphabet, are among the main reasons for overthrow of this script in Iranian civilization. The appearance of the Nasta’liq script and the overthrow of the Teimorans in Iran are also other factors of to be abandoned of this script in Iran.
