U+0BC0): MatraPos = 3 (above-base). - E (
U+0BC6) / EE (U+0BC7) / AI (U+0BC8): MatraPos = 1 (pre-base). - O (
U+0BCA) / OO (U+0BCB) / AU (U+0BCC): MatraPos = 5 (split — decomposed byApplyTamilReorder). - AU length mark (
U+0BD7): MatraPos = 2 (post-base) — emitted by U+0BCC split. - Halant is named PULLI in Tamil (
U+0BCD). - Visarga (
