Indic Syllabic Category - Pure Killer

Pure Killer is a classification for certain Indic script characters that are intentionally non-joining, meaning they do not visually connect to adjacent letters or marks in complex text shaping. This value applies to characters like the Bengali hasanta (virama) or the Devanagari nukta, which serve to suppress inherent vowels or modify consonants but are stripped of any inherent vowel or combining influence. Functionally, Pure Killer indicates that the character’s primary role is to kill a syllable’s default vowel sound without introducing its own phonetic value or triggering reordering. This ensures that shaping engines treat it as a neutral marker, preventing unintended ligature formation or vowel sign placement, thus preserving the intended syllabic structure in scripts like Bengali, Devanagari, and Tamil.
