Marchen script
The Marchen script was a Brahmic abugida which was used for writing the extinct Zhangzhung language.One extant document, a seal originally held at Tsurpu monastery, is written in the Marchen script.It also differs from other writing systems in the Bon tradition, such as Marchung, Pungchen, Pungchung and Drusha.A distinguishing feature of the Marchen script is the presence of a left-facing swastika, a symbol of the Bon religion, which is used both to write the letter nya and as a punctuation mark.[3] The Marchen script can be written in two different styles: one with thick angular letters and one with thin rounded ones.
