Re: WOFF-ACTION-197: Investigate font collections; how are glyf/hmtx shared in practice

Sergey,

The same is true of the OpenType Collections that we have built, all of which include one of more 'CFF ' tables. While I agree that it is theoretically possible to share outline data but to have different 'hmtx' (and possibly 'vmtx') tables, CFF makes this incredibly difficult. I have actually built a prototype that has different 'vmtx' tables, but unless the same is possible for 'hmtx', it's effectively a show-stopper. In other words, we have no plans at this time to deploy such fonts.

Best...
