The Tibetan script is used not only to write Tibetan as spoken in Tibet, but also the Dzongkha language spoken in Bhutan. Sanskrit is also transcribed into Tibetan characters. The earliest examples of Tibetan writing date to the eighth and ninth centuries. Tradition holds that the Tibetan script was created in the sixth century by a man named Thumi Sambhota, a member of a delegation sent to India by the king of Tibet to study Buddhism and the Indian languages.
 The information in the section on Tibetan comes from the lengthy character block description in the Unicode standard, pp. 240–248; Leonard W. J. van der Kuijp, “The Tibetan Script and Derivatives,” in The World's Writing Systems, pp. 431–436; and Nakanishi, pp. 88–89.
