Alphabets of unknown origin are, or were in a not too distant past, in use for the Berber language Tuareg (Tafinagh, a consonantal script possibly derived from the ancient Numidian alphabet), and some regional languages in Indonesia: Batak (in North Sumatra) and Buginese (in Southwest Celebes). The latter is supposed to have had its origins in Java, and thus be related to the scripts of Southern India.
