On Windows FontForge can be "tricky" to install.
I believe you are right. However, on Arch Linux it is enough to request fontforge package from repository and be done with it. Other Linux distributions probably do not make it any harder.
The only Linux distros that could possibly have hiccups would be RPM-based distros that require external third-party package repos to get a precompiled version. (I am not an RPM fan.)
This is a more laborious step for sure. From the poll results it seems we should stick to free licenses. Have any favorite fonts already?
DejaVu. It's Public Domain and has a reasonable initial set of monospace glyphs. It also looks good enough that folks actively use it in Roguelike projects.
There may be better-looking console/programming fonts. Better looking, more complete, and public domain? I think not.
There are very few reasons someone that favors an Apache or BSD license would disfavor a public domain license. Both allow embedding in commercial applications with closed-source modifications.
If we had a lot of GPL fans, we'd probably want something different. As it stands...
The other advantage of having our additions in the public domain: it's easy for other fixed-width fonts to steal them. If our primary goal is to get the missing glyphs in fonts, public domain aids that goal best.
