In the JSP page, use a page directive to set the content
type like this (example shown is for Chinese): <%@ page contentType = "text/html;charset=big5" %>
NOTE: This indicates the charset for both the JSP page itself as well as the
content that is sent back to the browser.
This means that you will have to author your JSP page using a text editor
that will allow you to save the JSP with the specified charset.
