Getting weird characters like Â instead of or â€™? Most likely there is a Character set problem. It can occur when a MySQL and PHP are upgraded or when data has been incorrectly stored or the application is sending an incorrect (or missing) character set to the browser. PHP doesn't yet support UTF-8 natively in its numerous string handling functions (version 6 will when released).
