      Fairfax HD is a halfwidth scalable monospace font for terminals, text
      editors, IDEs, etc. It supports many scripts and a large number of Unicode
      blocks as well as constructed scripts as encoded in the
      [Under-ConScript Unicode Registry][ucsur], pseudographics and
      semigraphics, and tons of private use characters.
