Ahh, probably a tab-completion error.  I have fixed this. :)

The problem you describe below is a known problem.  We are in the
process of preparing the first 3.2.0 beta, which will fix this
particular problem.  However, I don't think this is something that can
be fixed in 3.1.x, due to the current text/font engine design.

Even though you have a smoothly scalable Arial font, Qt will ignore it
because it is not a Unicode encoded font.

I agree with this, I will have to investigate this more with Lars, but
as I mention above, I don't think this will be fixable in 3.1.x.  3.2.0
and beyond will work properly though.
