This is a selective guide to Unicode-based fonts and script projects that are ideal for free/libre/open source (FLOSS) operating systems like GNU/Linux and FreeBSD. As a general policy, I include here only fonts that:
Contain Unicode CMAPs for mapping Unicode values to glyphs.
Can be downloaded and used legally for free.
Preference is given to high-quality vector fonts that have been released under SIL International’s Open Font License (OFL), the Free Software Foundation’s GNU General Public License (GPL), and similarly open licenses. I also include other important Unicode fonts, including a few notable shareware fonts where the authors request payment of a fee after an initial free evaluation. Although this document focuses on vector fonts that work well on free operating systems, these fonts will also work well on Unicode-capable Windows operating systems (Windows 2000 and XP) and on Apple OSX.
