WordPress 支持中文用戶名注冊

将以下php代碼複制到當前主題目錄下的functions.php中，即可讓WordPress支持使用中文用戶名注冊和登錄：

function MBT_sanitize_user ($username, $raw_username, $strict) {
 $username = wp_strip_all_tags( $raw_username );
 $username = remove_accents( $username );
 $username = preg_replace( '|%([a-fA-F0-9][a-fA-F0-9])|', '', $username );
 $username = preg_replace( '/&.+?;/', '', $username ); 
 if ($strict) {
 $username = preg_replace ('|[^a-z\p{Han}0-9 _.\-@]|iu', '', $username);
 }
 $username = trim( $username );
 $username = preg_replace( '|\s+|', ' ', $username );
 return $username;
}
add_filter ('sanitize_user', 'MBT_sanitize_user', 10, 3);
