I made this, but I dunno if it'll be used. Either way it was decided to give it to the public for use. Basically I took the font from sign.png and converted it to a font. I figured it would be very useful for those who want to script signs, but maintain a Graal feel to them.
Sadly, I don't think Graal downloads fonts by default, but I believe you can manage to do so via download packs. I don't know if I finished everything, but I believe I did.
Because it's vectorized, it isn't going to be crisp and clean like a bitmap font, but it seems good enough to me and I believe the benefits outweigh that negative.
edit: to install, simply drag it to your fonts folder and it should install it. If that doesn't work, google has lots of results to help you out.
