Something is wrong with the rendering of this PDF in Preview (or Quick Look). This is how it looks:
I can see it in Adobe Reader on Windows. I'm not sure what font it is using, and I have Office 2011 installed, so I have all of those fonts. Why is it displaying question marks on everything (except the text in the bottom left)?
I'm using Lion 10.7.1 on a 2010 17" MacBook Pro.
