バタックアルファベット

The Batak script, natively known as surat Batak, was used to write the Batak languages. It was spoken by several million people on the Indonesian island of Sumatra. The Batak script was probably derived from Pallava and Old Kawi scripts, which ultimately were derived from the  Brahmi 11000–1104D script, the root of almost all the Indic and Southeast Asian scripts. The script fell out of use and is now only used for ornamental purposes.
