C.14 Proposal to add Medievalist and Iranianist punctuation characters [SEI, Everson, L2/07-004]

Recommend to remove the "interpunctum circle" from the Medievalist proposal. Make an alias for it at U+25E6.

The SC did not have unanimous support for the following four characters and recommended that this issue be decided by the UTC in plenary session:

[110-C40] Consensus: Accept the following 16 punctuation characters from document L2/07-004 for encoding in a future version of the standard, and a future amendment of 10646:

• 2E1A.
• 2E1B, 2E1E, 2E1F: Change 3 names to be "swung dash with..." instead of being called tildes.
• 2E2A, 2E2C, 2E2E, 2E2F: These 4 fit into a class of multidot punctuation things
• 2E34, but change name to Reversed Question Mark, with an alias to "punctus percontativus".
• 2E38 "ring point" (see also Avestan).
• 2E40, 2E41; 2E46, 2E47; 2E48, 2E49.

NOTE: UTC did NOT accept these characters in the proposal:

• The rest of the U+2E2n and U+2E3n column. They need more discussion and further input from experts.

[110-A75] Action Item for Ken Whistler: Add 16 punctuation characters as per consensus 110-C40 to pipeline. See L2/07-004.

[110-A76] Action Item for Michael Everson: Update the proposal L2/07-004 with suggested name changes, and add "ring point" at U+2E38.

[110-A77] Action Item for Michael Everson, Debbie Anderson: Create a new proposal for Medievalist and Iranianist punctuation characters focused only on the positura and other related punctuation characters in L2/07-004 that were not accepted, for which questions remain, taking into account input from Odd Einer, Parkes, and other medievalists.

[110-C41] Consensus: Accept the four half-brackets documented in L2/07-004 at U+2E42 - U+2E45 for encoding in a future version of the standard and future amendment of 10646.

C.6 Reconsidering the encoding of I LONGA [Pentzlin, L2/07-032, L2/06-269]

[110-A81] Action Item for Rick McGowan: Write back to the author of L2/07-032 and say that the scripts subcommittee considers that the example PDF he cites shows a transcription from older Roman orthography into modern lower case. We don't see the need to add a lower case for the I LONGA or the other similar letters from L2/06-269. Ask him if he has any further input or evidence that I LONGA is being used unequivocally in a lower cased form, as opposed to a transcription that happens to use modern lower case. (For example, in the cited PDF accents were added, u/v and i/j were disambuguiated, etc.)

C.10 Rumi numerals [Lazrek, L2/06-291]

[110-A86] Action Item for Rick McGowan, Debbie Anderson: Follow up on Rumi with Lazrek and other scholars. We need to drive this to some kind of closure. Questions: is this set sufficient base for encoding? Try to move forward by next meeting. May need more information on how to actually implement these. See L2/06-291.

B.2.2.1 ISO/IEC CD 19757-7: Document Schema Definition Languages (DSDL) - Part 7: Character Repertoire Description Language [SC34, L2/06-397, L2/07-052]

[110-C45] Consensus: UTC thinks there are serious technical problems with the document ISO/IEC CD 19757-7: Document Schema Definition Languages (DSDL) - Part 7: Character Repertoire Description Language (SC34, L2/06-397). The grapheme cluster description is unnecessarily restrictive and makes it impossible to describe repertoires containing particular combining marks. UTC has serious concerns about any IANA registrations, and the registration process is unspecified.

[110-A93] Action Item for Eric Muller: Forward comments regarding ISO/IEC CD 19757-7: Document Schema Definition Languages (DSDL) - Part 7: Character Repertoire Description Language [SC34, L2/06-397, L2/07-052] on behalf of L2 before February 21, 2007.
