Encoding problem between jQuery and Java

Question

My encoding is set to ISO-8859-1.

I am making an AJAX call using jQuery.ajaxfor a servlet. The URL (after it was serialized by jQuery) is as follows:

https://myurl.com/countryAndProvinceCodeServlet?action=getProvinces&label=%C3%85land+Islands

The actual value of the label Åland Islands. When it comes to the servlet, the value I get is the following:

Ã\u0085land Islands

But that is not what I want. I would like it to be decoded before Åland Islands. I tried a lot of things (setting scriptCharset, trying to convert a string using getBytes(), but nothing works).
