Your browser -- and my browser -- did not autodetect the character encoding correctly. Switch to Unicode (UTF-8), and it should look fine. I used Firefox.
The reason our browsers don't autodetect the character encoding as utf-8 is because that page doesn't say it's utf-8. In that case browsers are allowed to assume it's latin-1.
If you want to get pedantic about it, the content is being served as text/html (as opposed to application/xhtml+xml) which means the XML declaration isn't valid.
Well, I'd like to know why it doesn't work. If that's pedantic, so be it.
Edit: I think people took this the wrong way. I mean it's not pedantic to find the real problem. We're all better off because the poster I'm responding to showed us the real problem.
