Anyone know if it would work if I open both .otf in FontForge, change
the family names to be e.g. "My Gotham Book" and "My Gotham Medium",
re-export them to OTF and then use e.g. font.family: "My Gotham
Medium" and don't set font.weight at all?
As you can understand, I'm a little desperate since we really need to
use these fonts for the UI, and we want to use the packaged Qt on
Ubuntu :/
