U+1BEA "ᯪ" Batak Vowel Sign I Unicode Character

U+1BEA "ᯪ" Batak Vowel Sign I is a combining mark used in the Batak script, which is indigenous to the Batak people of North Sumatra, Indonesia. This character functions as a vowel sign that modifies a consonant by adding an "i" sound, altering the syllable's pronunciation without being an independent letter. Rendered as a diacritical mark attached to the base consonant, it is part of the larger Batak Unicode block, which supports the traditional writing systems for four Batak languages: Toba, Karo, Dairi, and Mandailing. The inclusion of U+1BEA in Unicode helps preserve and digitize this endangered script, enabling modern text processing and digital communication for Batak linguistic heritage.
