Baybayin - Ancient Philippine writing system

"Baybayin is an old writing system that was used in the Philippines. It is an alphasyllabary belonging to the family of the Brahmic scripts. It was widely used in Luzon and other parts of the Philippines during the 16th and 17th centuries before being supplanted by the Latin alphabet. The characters are in the Basic Multilingual Plane (BMP) of Unicode, proposed to be encoded in 1998 by Michael Everson together with three other known indigenous scripts of the Philippines. In the 19th and 20th centuries, Baybayin survived and evolved into the forms of Tagbanwa script of Palawan, Hanuno'o and Buhid scripts of Mindoro, and was used to create the modern Kulitan script of the Kapampangan, and Ibalnan script of the Palaw'an tribe. - Wikipedia"
