vlad: existing spec for woff2 does not encode bit 6 for simple glyphs. Now there's a need to have it encoded since some renders care about it.
16:22:33 [Garret]
vlad: a couple of options to add it to the spec
16:22:48 [Garret]
vlad: use the reserved field in the woff2 header
16:22:59 [Garret]
vlad: or use the version field in the transformed glyf table
16:23:14 [Garret]
vlad: it would be split into a 16 bit version and a 16 bit flag field
16:23:22 [Vlad]
For WOFF2 update, see discussion thread at https://lists.w3.org/Archives/Public/public-webfonts-wg/2021May/0001.html
16:23:22 [Garret]
vlad: I like the second option the most
16:23:31 [Garret]
garret: agreed

action Garret: create a test woff2 file with the new flag6Bitmap added for legacy decoder testing
16:27:27 [trackbot]
Created ACTION-230 - Create a test woff2 file with the new flag6bitmap added for legacy decoder testing [on Garret Rieger - due 2021-06-01].
16:27:33 [Garret]
garret: I'd like to try running a woff2 using the new proposed encoding through an old decoder to make sure it doesn't cause problems so we can verify backwards compatibility
