There's no chance that someone could simply look at the new font files and reverse-engineer the spec, is there? Maybe it's as simple as "the file format is the same, you just have a larger unicode index instead of an 8-bit index"?

Possible, but more difficult, and if the team isn't in a hurry to release 3.0, I'm not in a hurry to fix vfdlib for 3.0. I'd rather have a spec in front of me than count on Doing the Right Thing with reverse engineering. Or at least someone with a blue nickname to say exactly what you just said about a larger unicode index.
