AFAIK, Qt _uses_ fontconfig, but I also noticed different behaviour of Qt 
applications.

Here, Konqueror doesn't show the same amount of glyphs that Firefox. Try for 
example:
http://en.wikipedia.org/wiki/Table_of_mathematical_symbols

In that page, the "proportional to" or "for all" symbols, appear as boxes in 
Konqueror, but are rendered OK in Firefox (well, in my computer at least). I 
tried playing with the default font settings in both, without seeing any 
change. I also made a test page which changes the font family with 
javascript, and still the same.

Then I made the attached program (compile with qmake -project; qmake; make), 
and still no luck. The japanese and greek characters are displayed, but the 
mathematical symbols are not.

I will try to investigate further, but I'm not very sure about where. :)
