I got an issue removing (reset the search/filter products in category) related to the hebrew language which is not passing correctly via querystrings. I got the same issue with UrlReWriting for categories using hebrew chars which is cuasing dead links. the problem is probably on this page : ProductSpecificationFilter.ascx.cs
but I did not manage to fix it and I need your help please
can you explain to me what you mean? I can give you example when this error comes up. when I go to laptops you can filter by Processor (Intel/AMD) . the translation for processor in hebrew is מעבד and when you click on that filter you can see the attribute on the address bar (url) correctly 51-notebooks.aspx?סוגמעבד=7 but when you move your mouse over the link to remove the filter you see this: 51-notebooks.aspx?ס××××¢××=7 as if the function that creates the link is not encoding the attribute name correctly.
