Section 2.2) Changes for new characters in 16.0, continued

[177-C45] Consensus: The UTC approves the code point change for GARAY HYPHEN to U+10D6E, from the conflicting U+10D6D approved by Consensus 171-C18. GARAY CONSONANT NASALIZATION MARK remains at U+10D6D. For Unicode version 16.0. See L2/23-234 Section 2.2.

[177-N5] Note: The PAG has corrected the Indic_Syllabic_Category range 13B8..113BA ; Vowel_Dependent (spanning 65539 code points) originally proposed in L2/22-031 and approved by Consensus 170-C9, to 113B8..113BA ; Vowel_Dependent (spanning three code points). For Unicode Version 16.0. See L2/23-234 Section 2.2.

[177-N6] Note: The first proposed line of UnicodeData.txt in L2/23-191 has one semicolon too many; U+A7DB should be the Simple_Lowercase_Mapping of U+A7DA, not its Simple_Titlecase_Mapping.

[177-N8] Note: The PAG has corrected the Titlecase_Mapping for U+1C8A CYRILLIC SMALL LETTER TJE from itself as approved by Consensus 172-C4 to U+1C89 CYRILLIC CAPITAL LETTER TJE. For Unicode Version 16.0. See L2/23-234 Section 2.2.

[177-N9] Note: The PAG has corrected the General_Category for U+10D6F GARAY REDUPLICATION MARK from Other_Symbol (So) as approved by Consensus 171-C18 to Modifier_Letter (Lm). For Unicode Version 16.0. See L2/23-234 Section 2.2.

[177-N10] Note: The PAG has corrected the General_Category for U+10D4E GARAY VOWEL LENGTH MARK from Other_Letter (Lo) as approved by Consensus 171-C18 to Modifier_Letter (Lm). For Unicode Version 16.0. See L2/23-234 Section 2.2.

[177-N11] Note: The Script_Extensions values suggested in L2/21-157R should not be added to the UCD; see the comments about a similar proposal in Section 6 of L2/23-012.

Section 2.3) Discrepancy between the numeric values for U+5146 and U+79ED

[177-A106] Action Item for Josh Hadley, PAG: Update the documentation for DerivedNumericValues.txt to indicate that the first-listed value of kAccountingNumeric, kOtherNumeric, or kPrimaryNumeric is what is used for the derived numeric value. For Unicode version 16.0. See L2/23-234 item 2.3.

[177-A107] Action Item for Ken Whistler, PAG: Update UAX #‍44, Table 9, description of Numeric_Value and the description following Table 10 to indicate that the value comes from the first-listed of kAccountingNumeric, kOtherNumeric, or kPrimaryNumeric. For Unicode version 16.0. See L2/23-234 item 2.3.

[177-A108] Action Item for Eric Muller, Laurențiu Iancu, PAG: update the UCDXML generator and data to list nv=Numeric_Value with at most one number. For Unicode version 16.0. See L2/23-234 item 2.3.

Section 2.6) Alphabetic combining letters

[177-C52] Consensus: Assign the property Alphabetic to the combining Latin letters U+0363..U+036F and U+1DD3..U+1DE6. For Unicode Version 16.0. See document L2/23-234 item 2.6.

[177-A127] Action Item for Robin Leroy, PAG: In PropList.txt, assign the property Other_Alphabetic to the combining latin letters U+0363..U+036F and U+1DD3..U+1DE6, and update derived properties accordingly. For Unicode Version 16.0. See L2/23-234 item 2.6.
