Line Break - Aksara Start
Aksara Start is a line break class that applies to the initial consonant or independent vowel glyphs in certain Southeast Asian scripts, such as Javanese, Balinese, and Sundanese. It indicates that a line break is permitted before the character but not after it, meaning the character must stay attached to the following syllable components. This behavior ensures that the base character remains grouped with its combining marks or subscript consonants, preventing visual splitting across lines in a way that would disrupt the script’s orthographic structure. Consequently, text rendering engines use this value to allow line wrapping only at syllable boundaries, typically before the starting glyph, while keeping the rest of the syllable intact on the same line.
