The problem is, it depend on the system (Mac and Win) and actually it depend on the Win version (98, ME, 2k, XP, etc...)! (a mention of this is in the WinNova dev log).

Wait, I'm not following - does it just default to the System font of the current platform/version?

I don't really know anything more than what has been said here. Which is already weird (something not consistent across different version of the same software?! That's normal, it's Microsoft)

Oh, okay, so it just goes with Windows's best guess (which, as would be expected, is often far from what you want - it probably tries to match just by name) on Windows. On Mac, I'll assume it defaults to Geneva.
