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 $error on failure or uploaded file name on success     */    public function upload() {        // Check for request forgeries        WFToken::checkToken() or die();        // check for feature access        if (!$this->checkFeature('upload')) {            JError::raiseError(403, 'Access to this resource is restricted');        }        $filesystem = $this->getFileSystem();        jimport('joomla.filesystem.file');                header('Content-Type: text/json;charset=UTF-8');        header("Expires: Wed, 4 Apr 1984 13:00:00 GMT");        header("Last-Modified: " . gmdate("D, d M_Y H:i:s") .
