Thomas, please ignore my reference to fastcam's Fontgen and try contacting Bahri Okuroglu.

Andy,

I was mistaken with the same name 'Fontgen'. I saw another Fontgen here.

But it seems both softwares are different.

Bahri Okuroglu says:

FontGen is a tool to create fonts for the graphical LCDs for your embedded project. It just takes the font installed on your Windows © PC and creates a C file representing that font for your embedded software.

Fastcam describes:

FontGEN provides True Type Font conversion into vector entities, which can then be saved as a CAM or a DXF file. It is particularly suited to Laser cutting, sign writing and marking applications. Built in arc fit technology generates continuous curves for reduced entity count and smooth vector results, which allows for better cut results.
