Chinese characters show up by default in WordPress as ???. In order to show them properly, you’ll need to edit the following lines in the wp-config.php file:
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');Comment out the lines by adding two forward slashes at the beginning of each line:
//define('DB_CHARSET', 'utf8');
//define('DB_COLLATE', '');Et voila! Well, you may need to re-publish your posts, but the Chinese characters should display properly now.
