How can i set XMLHttpRequest to support Unicode when it pass data by QueryString?

I use regular XmlHttlRequest, everything work fine except the unicode. How can i set that the query string will support unicode, (right now it return to c# '??????' when i pass unicode character (Hebrew)). I've tried to set the globalization setting to UTF-16 or Unicode in the web.config like this:

But it still pass '????'.

I attach pic of my code although its a XmlHttpRequest regular code like开发者_JAVA技巧 everyone know.

Thank you!

XMLHttpRequest won't modify URLs (other than removing invalid characters), you have to build the correct URL yourself. That's what encodeURIComponent function is good for:

xmlRequest.open("GET", "foo.apx?name=" + encodeURIComponent(name));
