I am using Windows XP. I have recently reinstall my OS. Now in every web browser on every website, wherever a HTML entity is used (e. g. #✓ - check mark), rectangles are shown instead.
When I enter this site: http://www.danshort.com/HTMLentities/index.php?w=dingb
I see this:

The same thing happens in Internet Explorer, Firefox, Chrome, etc.
What's wrong?
EDIT: Does anyone see check mark characters properly on this page (I mean text character not the image) ?
&(ampersand)? It appears you might be missing a unicode font? – w3d Nov 10 '10 at 9:24
