The Old Turkic block contains characters used in the Old Turkic script, also known as the Orkhon or Göktürk script, which was used for writing the Old Turkic language in inscriptions from the 7th to the 10th centuries CE in Central Asia. The script is a runiform alphabet, and this block includes all the characters needed to read the Orkhon inscriptions, which are some of the earliest known examples of Turkic writing. These inscriptions provide valuable information about the history, culture, and language of the early Turkic peoples and their empire..
