  "message": "unicode/norm: compose non-Hangul runes after a Hangul syllable\n\nreorderBuffer.compose switches to combineHangul as soon as it sees a\nJamo in the segment, and combineHangul only knows the two algorithmic\nHangul rules: its default case copies the rune through without ever\nconsulting the recomposition table. So once a segment starts with a\nHangul syllable (which decomposes to L V [T], hitting isJamoVT at index\n1), every table-driven composition later in that segment was silently\ndropped.\n\nThis was latent until Unicode 17, which is the first version to add\ncanonical compositions of starter + starter, where the first starter has\nccc\u003d0 and combinesBackward and so has no boundary before it and gets\npulled into the preceding Hangul syllable\u0027s segment. Twelve targets are\naffected: Tulu-Tigalari U+113C5, U+113C7, U+113C8, Gurung Khema\nU+16121-U+16128, and Kirat Rai U+16D68.\n\nFall back to the composition table in combineHangul\u0027s default case,\nmirroring what compose does.\n\nFixes golang/go#81021.\n\nChange-Id: I1a3c343e181aa0f8d19045084c16234d9c4da29f\nReviewed-on: https://go-review.googlesource.com/c/text/+/822080\nLUCI-TryBot-Result: golang-scoped@luci-project-accounts.iam.gserviceaccount.com \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: David Chase \u003cdrchase@google.com\u003e\nReviewed-by: Damien Neil \u003cdneil@google.com\u003e\n",
