Firefox has code to handle this.  For X11-ish platforms (since
you're talking about fontconfig), on the 1.8 branch (Firefox 1.5 and
Firefox 2), see:
http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/gfx/src/gtk/nsFontMetricsXft.cpp&rev=1.69.4.2&mark=1116-1118#1106
http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/gfx/src/gtk/nsFontMetricsXft.cpp&rev=1.69.4.2&mark=1116-1118#1106
or on the trunk (for Firefox 3, etc.), see:
http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/gfx/thebes/src/gfxPangoFonts.cpp&rev=1.94&mark=312-362,388#312

I'm not sure if I have any fonts that I could test this on, though.
Are there free fonts that it should work with?
