I also solved the Chinese character problem by following your suggestion. THANKS!!! This is my wp-config file for others to see where I edited the lines:
<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘xxx’); // The name of the database
define(‘DB_USER’, ‘xxxxx’); // Your MySQL username
define(‘DB_PASSWORD’, ‘xxxx’); // …and password
define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value
// define(‘DB_CHARSET’, ‘utf8’);
// define(‘DB_COLLATE’, ”);
