css2.1/t1202-counter-09-b.html
css2.1/t1202-counter-15-b.html 
css2.1/t1202-counters-09-b.html 
css2.1/t1202-counters-15-b.html 

All of them fail with DRT, but pass with QtTestBrowser.

I'm wondering if these 2 errors are related and are caused by fonts.
I'll take a deeper look.

Bug 50146 - [Qt] 4 css2.1/t1202-counter tests fail with Qt 4.7.1 

And in this one the display of t1202-counter-09-b.html in the
QtTestBrowser looks correct.  But when I add -use-test-fonts the
display is empty.
  $ $B/QtTestBrowser LayoutTests/css2.1/t1202-counter-09-b.html 
  $ $B/QtTestBrowser -use-test-fonts LayoutTests/css2.1/t1202-counter-09-b.html

Bug 50147 - [Qt] 4 fast/text tests fail with Qt 4.7.1 

When I display the format-control.html in the QtTestBrowser it looks correct,
But when I use the WebKit test fonts with the -use-test-fonts the zero width
chars are displayed as spaces.

Small test case that shows Georgian chars not displayed with QtTestBrowser -use-test-fonts

This could still be a font issue.  I can reproduce with a small
HTML test case with just a few Georgian characters in
geo_counter01.html attached.

When I look at the fonts available with "QtTestBrowser
-use-test-fonts" for Georgian, I only see 5 available and none of them
are marked with the Georgian language code (ka). If I don't use
the -use-test-fonts option, there are about 50 fonts available and many 
with the Georgian language code (ka).

I am not sure where to go next with these errors.  I think they are both
caused by the WebKit Test Fonts from 

   clone from git://gitorious.org/qtwebkit/testfonts.git

The bug is still valid on Qt 4.8 and Qt 5 too. I'll attach png diffs.
