Unicode Free Fonts
This page is for listing Unicode-compatible free fonts. Please put link to the site/download link if possible.
There are those who claim that if you embed a GPL font inside your document, (for example, in PDF, PostScript or LaTeX documents), it might mean you release your document under GPL. The FSF suggest adding an exception to the GPL license to better fit fonts. For more information see the FSF FAQ
More about fonts for free software can be found in font guide note though that some of the fonts there are under various non free licenses.
There appears to be a similar page to this on freedesktop.org, at Software/Fonts.
GPL licensed fonts
ToDo: Which of these fonts have the font licensing exception?

ToDo: Go over debian's font packages and add missing free fonts to the wiki
