Re: Some fields in OT header are not mentioned in WOFF spec

Hello Sergey,


> I noticed that there are three fields in OpenType font header that are not mentioned in WOFF spec: searchRange, entrySelector, and rangeShift.

First, it has to reference OpenType spec for calculation algorithm. And second, conformance requirements have to mention that these fields should be correct in original font to ensure complete roundtrip.

This was discussed on the WOFF call - as you know as you were there :)  -  and we agreed to your proposal. However, it would still be great to get a brief email from you agreeing that adopting your suggestion resolves your comment would be good, so we can link to the email to prove you are happy.
