    text
    copied!<p>I have an HTML page that looks like:</p> <pre><code>&lt;HTML&gt; &lt;meta http-equiv='Content-Type' content='text/html; charset=gb2312'&gt; &lt;BODY onload='document.forms[0].submit();'&gt; &lt;form name="form" method="post" action="/path/to/some/servlet"&gt; &lt;input type="hidden" name="username" value="麗安"&gt; &lt;!-- UTF-8 characters --&gt; &lt;/form&gt; &lt;/BODY&gt; &lt;/HTML&gt; </code></pre> <p>As you can see, the content of this page is UTF-8, but I need to send it with GB2312 character encoding, as the servlet that I am sending this page to expects from me GB2312.</p> <p>Is this a valid scenario? Because in the servlet, I couldn't retrieve these Chinese characters back using a filter that sets the character encoding to GB2312!</p> <p>I've created a sample Servlet:</p> <pre><code>package org.daz; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class EncodingServlet extends HttpServlet { private static final long serialVersionUID = 1L; private static final String ENCODING = "GB2312"; protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { setCharacterEncoding(request, response); String username = request.getParameter("username"); System.out.println(username); } private void setCharacterEncoding(HttpServletRequest request, HttpServletResponse response)throws IOException{ request.setCharacterEncoding(ENCODING); response.setCharacterEncoding(ENCODING); } } </code></pre> <p>The output is: <code>楹��</code></p>
