F3 font

F3 was a scalable font format created by Folio, Inc., which was later purchased by Sun Microsystems. It was supported by the Solaris X Window System in releases up through Solaris 10, and then support was removed.

Sun attempted to make F3 into an industry standard under the name OpenFonts, but lost out to the TrueType and PostScript font formats.

F3 fonts were recognized in Solaris Display PostScript as Type 7 fonts.
