I have designed a web multiannual web application in "UTF-8".
JSP Code: <%@ page contentType="text/html;charset=utf-8" %> <% request.setCharacterEncoding("utf-8"); // this can be added in Servlet Filter or in Action Form %> When JSP page is rendered it is found in IE > View... > Encoding > Unicode (UTF-8) > Is it possible to restrict the user to change encoding option in browser? Example: IE > View... > Encoding > Central European > Is there a way to identify in JSP or in Action File if the encoding has been modified at client side by user and show a message that "This application has been design to work in UTF-8 Encoding "
