Joomla!上传中文文件

国外的CMS系统一大问题就是上传中文附件。要么不支持上传，要么传上去不支持链接。

Joomla使用jce可以解决这个问题。

通过jce上传文件时，自动重命名，去掉中文即可。

在Joomla\components\com_jce\editor\libraries\classes\browser.php中，将upload函数中$name 重命名。

 /**
     * Upload a file.
     * @return array $error on failure or uploaded file name on success
     */

        WFToken::checkToken() or die();
