For a project (font or software or whatever) to be truly Free/Libre/Open Source, I think that everything should be provided that was used to produce the font. For example, the nice Charis SIL is released under the OFL by SIL in TTF format with quadratic curves. Internally, SIL works on the font as cubic splines. They even request that patches be submitted as cubic splines! However, when I contacted them, they refused to release the cubic curves that they internally use to produce the font. For this reason, I am planning my future font releases (those created solely by me) under the GPL+font exception. I would be interested to hear from other subscribers of the mailing list their opinion of the best way to handle this licensing issue. Best wishes, Stephen
