Discussion. UTC took no action at this time.

Section 5.1 Kirat Rai & Tulu-Tigalari vowel signs AI, Gurung Khema U: possible impact on some optimizations of normalization

[178-N3] Note: The following actions do not change the normalization algorithm or any properties that it depends upon. The impact is on the generation of “quick check” properties for certain new characters, which may be used by implementations to optimize normalization functions. See L2/24-009 item 5.1 and L2/24-013R section 5.

[178-A16] Action Item for Mark Davis, PAG: Modify the descriptions of the normalization quick check values in UAX #44 and UAX #15 to reflect the possibility of characters that have decomposition mappings and may change in NFxC normalization depending on context, and clarify that the NFxC_Quick_Check values are chosen for the quickCheck algorithm to yield accurate results. For Unicode 16.0. See L2/24-009 item 5.1.

[178-A17] Action Item for Robin Leroy, Markus Scherer, PAG: Set NFxC_Quick_Check=Maybe for characters like U+16D68 KIRAT RAI VOWEL SIGN AI which may change in NFxC normalization depending on context. For Unicode 16.0. See L2/24-009 item 5.1.

[178-A18] Action Item for Robin Leroy, Markus Scherer, PAG: Add test cases to NormalizationTest.txt that exercise composition with the components of U+16D68 KIRAT RAI VOWEL SIGN AI and similar characters. For Unicode 16.0. See L2/24-009 item 5.1.

[178-A19] Action Item for Markus Scherer, Ken Whistler, PAG: In the Unicode 16.0 alpha PRI and on the 16.0 beta & landing pages, point out the possibility of characters that have decomposition mappings and may change in NFxC normalization depending on context. For Unicode 16.0. See L2/24-009 item 5.1. Note: subject to implementation issues in ICU being resolved.

Section 6.1) UAX #14 LB28a -- confusing use of a literal value

[178-A20] Action Item for Robin Leroy, PAG: In rule LB28a of UAX #14, replace the use of the literal ◌ with the character class [◌], and add a note clarifying that the class contains the single character U+25CC DOTTED CIRCLE. For Unicode Version 16.0. See L2/23-009 item 6.1.

[178-A21] Action Item for Mark Davis, PAG: In UAX #29, change the definition of SB=STerm by excluding SB=ATerm. For Unicode Version 16.0. See L2/24-009 item 6.3.

[178-C11] Consensus: Give U+2024 ONE DOT LEADER the Sentence_Terminal property. For Unicode Version 16.0. See L2/24-009 item 6.3.

[178-A22] Action Item for Mark Davis, PAG: In PropList.txt, give U+2024 ONE DOT LEADER the Sentence_Terminal property. For Unicode Version 16.0. See L2/24-009 item 6.3.

Section 6.4) KIRAT RAI VOWEL SIGN AU will be added to Grapheme_Cluster_Break=V

[178-A23] Action Item for Rick McGowan, PAG: Reply to Charlotte Buff’s feedback ID20240107091023 in PRI #494 pointing out the presence of two points in U+16D67..U+16D6A. See L2/24-009 item 6.4.

Section 6.5) Legacy grapheme clusters are inconsistent with canonical equivalence

[178-C12] Consensus: Assign the Other_Grapheme_Extend property to eighteen characters (fourteen spacing viramas U+1715, U+1734, U+1B44, U+1BAA, U+1BF2, U+1BF3, U+A953, U+A9C0, U+111C0, U+11235, U+1134D, U+116B6, U+1193D, and U+11F41, two Vietnamese alternate reading marks U+16FF0 and U+16FF1, and two musical symbols U+1D166 and U+1D16D) in order to make all non-starters GCB=Extend. For Unicode Version 16.0. See L2/24-009 item 6.5.

[178-A24] Action Item for Robin Leroy, PAG: In PropList.txt, assign the Other_Grapheme_Extend property to eighteen pre-existing characters (U+1715, U+1734, U+1B44, U+1BAA, U+1BF2, U+1BF3, U+A953, U+A9C0, U+111C0, U+11235, U+1134D, U+116B6, U+1193D, U+11F41, U+16FF0, U+16FF1, U+1D166, U+1D16D), as well as to the Tulu-Tigalari vowel signs and looped viramas, and update derived properties. For Unicode Version 16.0. See L2/24-009 item 6.5.

Section 7.1) U+19DA inconsistent IDNA2008 status

[178-N4] Note: The idna2008derived files for versions 7.0 to 15.1 (inclusive) had U+19DA as PVALID which was in conflict with its IdnaMappingTable.txt IDNA2008 Status of XV8. The idna2008derived files have been corrected with 19DA as DISALLOWED.

Section 7.2) UTS #46: disallow IDCs via IDS_ properties not via Block

[178-A25] Action Item for Markus Scherer, Mark Davis, PAG: In UTS #46 section 6 step 2 “Specify the base valid set” replace the removal of \p{Block=Ideographic_Description_Characters} and \u31EF with the removal of [\p{IDS_Unary_Operator}\p{IDS_Binary_Operator}\p{IDS_Trinary_Operator}].
