I think there's something screwed up with the server setup and the character encodings. Or in the way they're converting the stories. I see the same things.

If you look at what encoding the browser thinks the page is (View->Character encodings in firefox and Page->encoding in IE8) it says UTF8. But is you manually change the encoding the browser is using to Western European (ISO-8859-1 in firefox) it fixes the issue and everything looks fine. So something is telling the browser to display it using the wrong character encoding.
