This document presents information that will assist font developers in creating fonts for the Tibetan scripts covered by the Unicode Standard 6.0. The Tibetan script is used for writing Tibetan in several countries and regions throughout the Himalayas. It is also used to write Balti, Bumthangkha, Khengkha, and oher languages. It has also been used to transliterate Sanskrit and Chinese. The Tibetan writing system was based on a North Indian form of the Brahmi script and is said to have been developed to bring Buddhism from India to Tibet. Two distinctive styles have emerged: a formal style used for books and inscriptions (called dbu can ‘with a head’) and a cursive or calligraphic style (dbu med ‘acephalous’) commonly used in hand-written contexts. Tibetan script is a parent script of Phags-pa, Limbu, and Lepcha, which have separate encodings and shaping requirements.
