The license for the compiled fonts is covered by the above GPL terms with the GNU font embedding exception, as follows:
As a special exception, if you create a document which uses this font, and embed this font or unaltered portions of this font into the document, this font does not by itself cause the resulting document to be covered by the GNU General Public License. This exception does not however invalidate any other reasons why the document might be covered by the GNU General Public License. If you modify this font, you may extend this exception to your version of the font, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.
When I use this fontface in a game, does the game fulfill the definition of being a "document" or do I need to license the game under the GPL?
Details about how the font is used:
- The game engine would use the font-face to render text on GUI elements.
- I might create 2d images which include characters from that font-face and use these as textures in the game.
