It's definitely not that code which would allow you to do that.
HikaShop already uses that code (file administrator/components/com_hikashop/classes/product.php):
function addAlias(&$element){
if(empty($element->product_alias)){
$element->alias = $element->product_name;
}else{
$element->alias = $element->product_alias;
}
$app = JFactory::getApplication();
if(method_exists($app,'stringURLSafe')){
$element->alias = $app->stringURLSafe(strip_tags($element->alias));
}else{
$element->alias = JFilterOutput::stringURLSafe(strip_tags($element->alias));
}
}
It's actually used to handle UTF8 characters in URLs, not to transliterate Russian names.
If you have an example of code, we can potentially add an option, but it's definitely not that code.
