I see something that looks like a bug. Before reporting it officially, I would like to have some advice here.
The problem is about the printing of the characters "°C".
Step to reproduce:
1 - download and open this doc file: http://dl.free.fr/gAjvNTEFN
2 - you will see that it display something like this:
3 - Print it with pdfCreator, then open the pdf file. The display is now like this:
This is not correct, the "°" and the "C" should not be collapsed.
Hope someone has a godd advice on this problem.
 I do not understand why my images are not displayed in the final post??? I see them in edition mode!
this bug is known already and seems to be a GhostScript bug. We have created an item in their bugtracker and hope that it will be fixed soon.
Here is the GS bug item: http://bugs.ghostscript.com/show_bug.cgi?id=691006
PS: The image display is diabled due to security reasons.
A workaround would be to use Tahoma or Verdana for the Degree symbol
I have read some where that GhostScript bug problem has solve.
But I think if we use different font then it will work.
We thought it was fixed, but is seems to be there. Please notice this workaorund for the moment: http://www.pdfforge.org/content/degree-symbol-overlaps-following-character
We hope to finally fix this in PDFCreator 1.2.1
