  "message": "unicode/norm: let any starter block composition in compose\n\nreorderBuffer.compose only refreshed s, the index of the last starter,\ninside the ii.combinesBackward() branch. A rune that does not combine\nbackward therefore left s pointing at whatever starter preceded it, and\nthe next backward-combining mark composed with that stale starter even\nthough an intervening starter should have blocked it.\n\nFor example, NFKC of U+16D68 U+FB01 U+113C2 U+0300 U+0316 decomposes to\nU+16D68 f i U+113C2 U+0316 U+0300. U+0316 does not combine backward, so\ns was left pointing at the \"i\" rather than at the starter U+113C2, and\nU+0300 composed with the \"i\" to give U+00EC, dropping a code point and\nproducing a string that is not canonically equivalent to the input.\n\nUpdate s on every iteration, as combineHangul already does.\n\nFixes golang/go#81001.\n\nChange-Id: I4d2332b4a0c44d60bd0961036391617a728c12df\nReviewed-on: https://go-review.googlesource.com/c/text/+/822081\nReviewed-by: David Chase \u003cdrchase@google.com\u003e\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Damien Neil \u003cdneil@google.com\u003e\n",
