I never run into this problem before. I am using the Events plugin and on the 'More' and 'More Information' links for each event listed there is a » that isn't rendering properly. While technically this isn't strictly a WP question, it is the first time I have seen this and this is the first major WP site I have worked on.
Could somebody take a look at: http://wmu.texasbaptists.com/wordpressmu/ and help me understand why the » is rendering as a question mark in a diamond on the Mac and an empty square on a WinPC? (Look for the 'More Information' link.
This renders this way on my custom theme and on the default wp theme.
