Magento为类别重新生成url键

我必须为所有类别重新生成所有url键。 当我添加一些主要类别时，我使用论坛中的一种方式复制了它们。 一切都很顺利，但当我复制了大约2万个类别时，我看到：当名字上有波兰语字母时，其余的都被删掉了： 例子： 类别名称：Części Karoseryjn 应该是：czesci karoseryjne 复制后：cz

类别名称：Próg zwalniajacy 应该是：prog zwalniajacy 复制后：pr

我在波兰语论坛上找到了修复它的方法（用波兰语字母），但它只适用于新添加的类别。 现在，当我选择任何类别时，清除url键并单击保存-命名是确定的，但是。。。。。。。有2万个类别… 有人能写下如何修复它吗？

require_once 'app/Mage.php';
Mage::app('default'); // Default or your store view name.

//get a new category object
$category = Mage::getModel('catalog/category');
$category->setStoreId(0); // 0 = default/all store view. If you want to save data for a specific store view, replace 0 by Mage::app()->getStore()->getId().

//if update
if ($id) {
  $category->load($id);
}

$general['name'] = "My Category";
$general['path'] = "1/2/23"; // catalog path
$general['description'] = "Great My Category";
$general['meta_title'] = "My Category"; //Page title
$general['meta_keywords'] = "My , Category";
$general['meta_description'] = "Some description to be found by meta search robots. 2";
$general['landing_page'] = ""; //has to be created in advance, here comes id
$general['display_mode'] = "PRODUCTS_AND_PAGE"; //static block and the products are shown on the page
$general['is_active'] = 1;
$general['is_anchor'] = 0;
$general['page_layout'] = 'two_columns_left';

//$general['url_key'] = "cars";//url to be used for this category's page by magento.
//$general['image'] = "cars.jpg";


$category->addData($general);

try {
    $category->save();
    echo "Success! Id: ".$category->getId();
}
catch (Exception $e){
    echo $e->getMessage();
}
