Batak

Batak is a Unicode block containing characters for writing the Batak dialects of Karo, Mandailing, Pakpak, Simalungun, and Toba.

The Batak script, natively known as surat Batak, surat na sapulu sia (the nineteen letters), or si-sia-sia, is an abugida used to write the Austronesian Batak languages spoken by several million people on the Indonesian island of Sumatra. The script may derived from the Kawi and Pallava script, ultimately derived from the Brahmi script of India, or from the hypothetical Proto-Sumatran script influenced by Pallava.
