F.1 Section 2.2

[175-A67] Action Item for Robin Leroy, EDC: Publish the annotated version of the UAX #14, Unicode Line Breaking Algorithm, as a new UTN (Unicode Technical Note).

F.1 Section 2.5

[175-C20] Consensus: Change the name of the informative property created by Consensus 174-C2 to NFKC_Simple_Casefold, with a low line between the words Simple and Casefold. Its alias NFKC_SCF and its definition are unchanged. For Unicode Version 15.1.

[175-A69] Action Item for Ken Whistler, PAG: Update the name of the property NFKC_SCF in the Property Table of Unicode Standard Annex #44, Unicode Character Database, for Unicode Version 15.1. See document L2/23-079 item 2.5.

F.1 Section 4.1

[175-C21] Consensus: The UTC will not add further characters to the Unicode Standard with both (a) canonical decompositions, and (b) Bidi_Paired_Bracket_Type ≠ None. Unicode will also not add further characters where the canonical decompositions *contain* characters whose Bidi_Paired_Bracket_Type ≠ None. See L2/23-079 item 4.1.

[175-A70] Action Item for Manish Goregaokar, PAG: Change UAX #9 to point out that an implementation of the UBA need not perform normalization / canonical equivalence in general, and explicitly list the pairs of paired bracket characters relevant for canonical equivalence and merely motivate this list via normalization; note that this list is immutable unless Unicode overturns precedent 175-C21; for Unicode Version 15.1. See L2/23-079 item 4.1.
