The Xft library provides support for antialiased TrueType fonts, full Unicode, and an unbraindamaged font selection mechanism for X11.

It relies on fontconfig [http://www.fontconfig.org], FreeType [http://www.freetype.org], and the X Render extension (although it will still work if XRender is not available on the server).  Xft 2.0 is included in most recent Linux distributions (circa May 2003).  Mozilla, Qt, and GTk have all been updated to use Xft.

Experimental support for Xft in Tk 8.5 has been committed to the CVS HEAD (31 May 2003).
See also patch #535541 [http://sourceforge.net/tracker/?func=detail&aid=535541&group_id=12997&atid=312997].
There are still (31 May 2003) a few quirks and bugs to be worked out, but overall it works pretty well.

To enable Xft support, run:

    sh ./configure --enable-xft
    make clean
    make

Many thanks to Keith Packard for contributing the original code.
Blame [Joe English] for the stuff that doesn't work right yet.
