DejaVu

The following text is from the project home page: http://dejavu.sourceforge.net/wiki/index.php/Main_Page

The DejaVu fonts are a font family based on the Bitstream Vera Fonts release 1.10. Its purpose is to provide a wider range of characters while maintaining the original look and feel through the process of collaborative development. The family is available as TrueType? fonts and also as packages for various operating systems including handhelds.

See ConvertingTrueTypeFonts to convert to Type 1 and build the groff font files. Or if you just want some pre-built stuff, see http://home.alltel.net/kollar/groff/#dejavu
