I think that it would be a fun project to make a font creator. It's only currently possible in DBPro but it would indeed be handy. Kenjar makes a good point but it's the responsibility of developers to only sell something they have the rights to.
I will seriously consider making one of these at some point. I might start with a simple automatic version that just churns out a basic font set and see where it goes from there. I have a lot of the necessary code from another project.
I agree it's an art, but so is programming
I have some solid ideas how to achieve this in DBPro.
