Proposed Script tag additions

[Levantovsky, Vladimir]

Dear all,

I would like to suggest for your review and consideration the following proposed schedule for a new OFF amendment, which is based on the approved schedule of the WG11 (MPEG) meetings:

January 24-29, 2011 - Working Draft amendment
March 21-25, 2011 - Proposed Draft amendment and issue combined PDAM / registration ballot (3 months)
July 18-22, 2011 - Final Proposed Draft amendment (4 months ballot)
Nov. 28 - Dec. 02, 2011 - Final Draft Amendment (2 month yes/no ballot)
Feb. 6-10, 2012 - publication

Some noteworthy points:

-          An attempt to accelerate the amendment and produce PDAM in January would not change the final outcome - the ballot would not be closed until the end of April, which will push the FPDAM date to July;

-          Starting with the working draft will allows us some time to review the additional proposals (if any) and incorporate them in the current amendment based on consensus;

-          Any proposed new features should be submitted to this AHG list no later than early January to allow sufficient time for discussions. The agreed proposals would have to be submitted to WG11 no later than Jan. 17th;

-          We will have a chance to review and improve the Working Draft amendment and improve it before promoting the document to the Committee Draft stage in March.

Please submit your ideas and proposals for new features and/or improvements and clarifications to the spec for AHG consideration.

Thank you and regards,
Vladimir

Subject: [mpeg-OTspec] Proposed Script tag additions




The most recent versions of Unicode (versions 5.2 and 6.0) have added several new script tags that are missing in the second edition of ISO/IEC 14496-22 "Open Font Format" specification and the corresponding version of the OpenType 1.6. The current list of script tags can be found in the subclause 6.4.1 of 14496-22 and is available here: http://www.microsoft.com/typography/otspec160/scripttags.htm.

The newly defined Unicode script tags include the following:
