The Batak script (natively known as Surat Batak (), Surat na Sampulu Sia (), or Sisiasia) is a writing system used to write the Austronesian Batak languages spoken by several million people on the Indonesian island of Sumatra. The script may be 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.
History
The Batak magicians and priests or datu used the Batak script mainly for magical texts and divinatory purposes. It is unknown how many non-specialists were literate in the Batak script, but judging from the widespread tradition of writing love laments, especially among the Karo, Simalungun, and Angkola-Mandailing Batak, it is likely that a considerable part of the non-specialist population was able to read and write the Batak script. After the arrival of Europeans in the Batak lands, first German and (from 1878 onward) Dutch missionaries taught the Batak script alongside the Roman script in schools, and teaching and religious materials were printed in the Batak script. Soon after the first World War the missionaries decided to discontinue printing books in the Batak script. The script quickly fell out of use and is now only used for ornamental purposes.
Origin
The Batak script was probably derived from Pallava and Old Kawi scripts, which ultimately were derived from the Brahmi script, the root of almost all the Indic and Southeast Asian scripts.
Structure
Batak is written from left to right and top to bottom. Like all Brahmi-based scripts, each consonant has an inherent vowel of , unless there is a diacritic (in Toba Batak called pangolat) to indicate the lack of a vowel. Other vowels, final ŋ, and final velar fricative are indicated by diacritics, which appear above, below, or after the letter. For example, /ba/ is written ᯅ ba (one letter); /bi/ is written ᯅᯪ ba-i (i follows the consonant); /baŋ/ is written ᯅᯰ ba<sup>ng</sup> (ng is above the consonant); and /biŋ/ is ᯅᯪᯰ ba-i<sup>ng</sup>. Final consonants are written with the pangolat (here represented by "#"): /bam/ is ᯅᯔ᯲ ba-ma-#. However, /bim/ is written ᯅᯪᯔ᯲ ba-ma-i-#: phonetically, the first diacritic modifies the first consonant, and the second modifies the second consonant, but both are attached to the second consonant.
Unlike most Brahmi-based scripts, Batak does not form consonant conjuncts.
Basic characters
The basic characters are called surat. Each consonant has an inherent vowel of . The script varies by region and language. The major variants are between Karo, Mandailing/Angkola, Pakpak/Dairi, Simalungun/Timur, and Toba:

ᯤ and ᯥ are only used for open syllables. Some manuscripts use ᯀᯪ and ᯀᯮ instead of ᯤ and ᯥ even there: ᯘᯤ or ᯘᯀᯪ sai, ᯘᯥ or ᯘᯀᯮ sau.
In Angkola/Mandailing, the letter ᯂ has the value /ha/ if it is in syllable initial position and /k/ in final position. The tempi diacritic is optionally used to distinguish ᯄ᯦ /ka/ from ᯄ /ha/ and ᯚ᯦ /ca/ from ᯚ /sa/.
Diacritics
Diacritics are used to change the pronunciation of a character. They can change the vowel from the inherent , mark a final [velar nasal] , mark a final velar fricative , or indicate a final consonant with no vowel:

Tompi
In Mandailing, the diacritic tompi can be used to change the sound of some characters:

| 30px|link=|alt=A
|}
Placement of diacritics for Ng and H
The diacritics for Ng (30px|link=|alt=-Ng) and H (30px|link=|alt=-H) are usually written above spacing vowel diacritics instead of above the base character.<br>
Examples: baseline|30px|link=|alt=Ping ping, baseline|30px|link=|alt=Pong pong, baseline|30px|link=|alt=Peh peh, and baseline|30px|link=|alt=Pih pih.
Diacritic reordering for closed syllables
Vowel diacritics are reordered for closed syllables (that is, syllables where the final consonant has no vowel). Consonants with no vowel are marked by the Batak pangolat or panongonan diacritic, depending on the language.
When they are used for a closed syllable (like "tip"), both the vowel diacritic and the pangolat or panongonan are written at the end of the syllable.
Examples of closed syllables using pangolat:

Punctuation and ornaments
Batak is normally written without spaces or punctuation (as scriptio continua). However, special marks or bindu are occasionally used.
They vary greatly in size and design from manuscript to manuscript.

Unicode
Batak script was added to the Unicode Standard in October 2010 with the release of version 6.0.
The Batak script was registered in Unicode by Uli Kozok, a German scholar of Batak literature. Before being documented by Uli Kozok, there were several versions of the Batak script based on Batak sub-ethnic groups, including Toba, Karo, Simalungun, Mandailing, and Pakpak. Uli succeeded in unifying the Batak script, with minor differences considered as variations.
Currently, the Batak script is listed in Unicode with the status of a limited use script. For its status to be elevated to recommended, evidence must be submitted to Unicode showing that the Batak script is still in use.
Character input is phonetic, with the visual output reordered per the description above. For example, lon ᯞᯬᯉ᯲ is entered LON# but displays as LNO#. If the text is entered LNO#, a dotted circle will separate the pangolat from the O, indicating an encoding error.
Block
The Unicode block for Batak is U+1BC0–U+1BFF:
