Proposed changes to the OFF specification

Sorry for our delay in responding to this proposal. Microsoft would like to delay this proposal so that we can do more investigation. When originally asked, we said that all known implementations follow the current version of the Panose specification. We now believe that some implementations (internal and external to Microsoft) may still follow version 1 of the Panose specification. Version 1 only contained support for Latin Text and Display faces and the Opentype specification was written based on Version 1. If this is the case, we may need to mitigate this problem by updating the version of the OS/2 table and adding a new field to support Panose 2.0.

Subject: Proposed changes to the OFF specification

Dear all,

It's been a long time since our last activity on this list. The next WG11 meeting is in two weeks, and I would like to bring to your attention the liaison statement from SC34/WG$ submitted to WG11 (see attached) where a proposal is made to make changes to the existing specification and to remove the list of property names from the current description of OS/2 table instead simply referring to the original Panose specification.

I would like to ask for your input and opinions on this suggested change.

Thank you,
