The Sogdian script was used by the Sogdian people during the 4th to 10th centuries CE and is closely related to Old Sogdian, evolving from earlier forms of the script. As one of the major scripts of Central Asia, it was used to write the Sogdian language, which was widely spoken along the Silk Road. Sogdian texts cover a wide range of subjects, including religious texts from Buddhism, Zoroastrianism, and Manichaeism, as well as secular documents like letters, contracts, and trade records. The inclusion of the Sogdian script in Unicode is crucial for historians and linguists studying the cultural and economic exchanges that occurred along the Silk Road. By providing a way to digitally encode these texts, Unicode helps ensure the preservation of this historically significant script, contributing to our understanding of the ancient world and the connections between East and West..
