Courier [Adobe] that comes with XFree86 is a bit mapped font.  Try IBM Courier or 
BitStream Courier which are scalable Type1 fonts.

I don't know what would cause that unless the font actually has the blank character for 
that character code.

Qt has a font selection algorithm that scores the fonts and is supposed to select the best 
substitution.  If that fails, it will select the default font set in: "qtconfig" and the 
default there is Helvetica.

As I said above, try the two Type1 Courier fonts that come with XFree86.

I note that I have also had problems with Qt and Courier.  I seems to get confused about 
which one to use.
