			Alternatively, you maybe adding a new clean install Moodle version to an existing web server and the UTF8 check error will not allow you to proceed. Use [[phpMyAdmin]] to help you. This web client is available as a plugin for Moodle or through your web hosting control panel. Using this program, create an empty database (for example moodle199) and make sure "MySQL connection collation" is a utf8 entry, such as utf8_general_ci. Go back to the Moodle installation screen with the check error, hit the previous button on the bottom and make sure the databae has the same name as your new empty database (for example moodle199).
