[MPEG-OTSPEC] AHG kick-off and AHG meeting announcement

[Vladimir Levantovsky]

Dear all,

Following up on my previous email, I am happy to let you know that the text
of the updated WD of ISO/IEC 14496-22 5th edition Open Font Format
<https://www.mpeg.org/wp-content/uploads/mpeg_meetings/144_Hannover/w23170.zip>
is
now available for public review.

While integrating the proposed changes related to newly introduced
Condition Table Format 2 (see subclause 6.2.9) I realized that the current
description of the Condition Table is technically incorrect since it is
referring to non-existent version number of the ConditionSet table (see
second paragraph). It appears that the corresponding parts of the OpenType
spec
<https://learn.microsoft.com/en-us/typography/opentype/spec/chapter2#featurevariations-table>
have already been modified at some point but these text
modifications/corrections have not been proposed to the SC29/WG3 yet.

I also would like to remind you that we need to schedule the AHG Zoom call
to further discuss the changes necessary to make progress on the "Beyond
64K glyphs" proposal summarized in the "Technologies under consideration
for ISO/IEC 14496-22 5th edition Open Font Format
<https://www.mpeg.org/wp-content/uploads/mpeg_meetings/144_Hannover/w23265.zip>"
document. Our available options are to schedule the first call either
during the week of Nov. 27 or the week of Dec. 4 - please respond to this
email to indicate your availability and specific date preferences for the
call.
(I am hopeful that the additional changes we discussed during the last WG
meeting would already be integrated in the updated version of the proposal
that we can review and finalize during the call.)

Thank you,
Vladimir
