You would also do the same thing you are doing with all your web pages, send the desired CHARSET in the meta tags. This is should be done as a matter of course to ensure the user always views your web pages in the correct font and to prevent a malicious third party from using your wesbite to attack users by taking advantage of UTF-8 encoding to trick their browser into using a different CHARSET. I learned this from security gurus attending the Feb 12-13 Vancouver PHP Conference 2007.
