font issues

Using a uniform fonts on Unix (SunOS/Linux) systems.
Want our applications to use the same font on every machine. In our pre Qt (X11)
implementation we used a hardcoded X font
(misc-fixed-bold-r-normal-13-120-75-75-c-80-iso8859-1). This font worked
and looked the same on every system. We want to use this same font again in
our Qt applications, so we did the following:

QFont font;
font.setRawName("misc-fixed-bold-r-normal-13-120-75-75-c-80-iso8859-1");
qtapp->setFont(font);

This works on most of the systems. However, on some older Linux systems
(CentOS release 3.8), the font letters appear as empty characters (i.e. no
texts are displayed at all). When checking the availability of this font
(e.g. using xfontsel), the font is available on the system.

The attached example program, already reproduces this problem. When typing in
the appearing QTextEdit, on the problem machines, only spaces appear when
typing. We tried calling setRawMode(true). Then a font is displayed, but it's
not the correct font (not bold).

When font.exactMatch() is called, it returns false, but it also returns false
on the problem machines, so there's no way to determine it went wrong.
