Yup, almost certainly an encoding problem at the server.
FF2 with the Web Developer plug-in shows in the Response Header: Apache 1.3 serving text/html. The meta headers show: content="text/html; charset=iso-8859-1".
Right there you're guaranteed to have problems for any characters outside of ISO-8859-1.
A good first step for all web masters: serve UTF-8.
