I used to work with Fontlab Studio to design and compile my fonts. Years have passed and my former Fontlab install vanished into the voids of a crashing harddisk.
Now that I'm gaining interest in font-design again, I used and abused the usual search engines, but I have not managed to find any free or open-source software out there with alike functionality which Fontlab offers.
Therefore I would love to know: "Is there any open-source alternative to Fontlab out there?"
(Preferably, it should be able to run on a Microsoft Windows operating system.)
