[Cooker] good fonts / bad fonts

[Combelles, Christophe (MED, ALTEN)]

Does anybody know what is the difference between a good font and a bad font?

(The rendering engine has an important job, but the font is important too.)
I have found that the program pfaedit is included by default in mandrake, it seems to be a very good tool to build fonts.
But is having a good tool enough to build a good font ?
