Problem in decoding parameters in get method, JSP_问答_开发者

Here how jsp page is called.

eventMap.jsp?venue=%C4%B0ndigo

This is the line in eventMap.jsp which I get venue parameter:

var venue="<%= URLDecoder.decode(request.getParameter("venue"),"UTF-8") %>";

Unfortunately this is the result in final javascript:

var venue="Ä°ndigo";

How can I use encoding properly in jsp page in order to get decoded value correctly (İngido).

Edit: Whole eventMap.jsp

Decoding of the GET query string is handled by the servletcontainer, not by the Servlet API. It's unclear which servletcontainer you're using, so I can't give a detailed answer. In for example Tomcat, it's configureable by URIEncoding attribute in the <Connector> element in /conf/server.xml.
