The page is character encoded in ISO-8859-1, but the web server is reporting it as UTF-8. (Probably because the web page was written before Unicode became a common concern of webmasters, it dates back to 1999.)
In Firefox, select View->Character Encoding->Western (ISO-8859-1). In Safari, select View->Text Encoding->Western European.
(FYI, this shows up this way on Windows systems too. It's not MacRoman or Windows-1252 to blame this time.)
