F.1 1.1 Defective decision 174-C22 on the name of Tolong Siki letters. [#346]

[182-C17] Consensus: In reference to decision 174-C22, the UTC asserts that the names of all Tolong Siki consonants U+11DB6..U+11DD8, including U+11DC5, are the ones without a final A, as given on pages 8 and 9 of L2/23-024. The inconsistent names given elsewhere in that proposal are not used. See L2/25-006 item 1.1.

Discussion of potential changes to drafting of recommendations to avoid ambiguous decisions.

Discussion of the status of non-property data in the UCD.

F.1 3 Collation

F.1 3.1 UCA implicit weights for Tangut blocks [#342]

[182-C18] Consensus: For Tangut default collation with implicit weights, split Tangut components from Tangut ideographs into separate ranges. Sort Tangut components between Tangut ideographs and Nüshu. For Unicode Version 17.0. See L2/25-006 item 3.1.

[182-A54] Action Item for Ken Whistler, PAG: For Tangut default collation with implicit weights, split Tangut components from Tangut ideographs into separate ranges. Sort Tangut components between Tangut ideographs and Nüshu. For Unicode Version 17.0. See L2/25-006 item 3.1.

[182-A55] Action Item for Markus Scherer, PAG: In UTS #10, change the text to describe that Tangut components are sorted between Tangut ideographs and Nüshu. For Unicode Version 17.0. See L2/25-006 item 3.1.

F.1 4 Security

F.1 4.1 Rare Han characters should not be “recommended” for identifiers [#354]

Long discussion of stability. Identifier_Type is not covered by the stability policy (contrary to the ID_ and XID_ properties, used in the definition of default identifiers).

Discussion of applications.

Roll call adjustment: SIL (associate member) no longer present (4.5 voting members represented).

[182-C19] Consensus: Assign Identifier_Type values to Unified_Ideograph characters according to whether they are in common use. Keep exactly those Unified_Ideograph characters as Identifier_Type=Recommended which are documented in RZ-LGR-5 and listed in L2/25-031. For all other Unified_Ideograph characters set Identifier_Type=Uncommon_Use. For Unicode Version 17.0. See L2/25-006 item 4.1.

[182-A56] Action Item for Asmus Freytag, Markus Scherer, PAG: In UTS #39 data, assign Identifier_Type values to Unified_Ideograph characters according to whether they are in common use. Keep exactly those Unified_Ideograph characters as Identifier_Type=Recommended which are documented in RZ-LGR-5 and listed in L2/25-031. For all other Unified_Ideograph characters set Identifier_Type=Uncommon_Use. For Unicode Version 17.0. See L2/25-006 item 4.1.

F.1 6 Proposed updates

Markus Scherer briefly presented this section of L2/25-006.

F.2 PRI #509 Proposed Draft UTS #58, Unicode Link Detection and Serialization

Mark Davis discussed the accumulated feedback on PRI #509. Feedback from ID20241206213148 has been addressed. Mark Davis noted that addressing feedback ID20241218024123 risks making the test data hard to read in most text editors, whereas bidirectional concerns are largely independent of link detection.

Discussion of ZWNJ.

The properties and algorithms group will discuss whether a list of Wikipedia pages with non-ASCII URLs should be included in the test data.

Mark Davis presented the Proposed Draft UTS #58, renamed to Unicode Link Detection and Serialization.

Discussion of versioning. Proposed Draft UTS #58 should be versioned as a synchronized UTS. While the draft data files may be adjacent to the draft, upon publication, the data files should be in the versioned directory.

[182-A58] Action Item for Asmus Freytag, Ken Whistler, PAG: In UTR #33, propose wording describing stable Unicode Technical Standards with synchronized data.

[182-A59] Action Item for Markus Scherer, PAG: Consider the future maintenance of the structure of data files in the versioned data directory, considering existing and new specifications that are synchronized with versions of Unicode.

The plan is to move this document to Draft status at UTC #183, and possibly to final publication at UTC #184, synchronized with 17.0. The draft should be updated to include the version 17.0.
