Extended characters in PDF

Hi David, all

The latest PDF seems to still have some trouble with non-Latin-1 characters
It still has the wrong characters I mentioned here:

The same example looks fine in the HTML output, so the issue is related to some some PDF generation problem.

If there is no way to solve it quickly, we may want to replace the text with something that works for PDF.

Cheers,
-yves
