title: error-page directive in web.xml does not display UTF8 properly
body: <p>I have an application web.xml with the following entry:</p>
  
  <pre><code>&lt;error-page&gt;
      &lt;error-code&gt;404&lt;/error-code&gt;
      &lt;location&gt;/system_files/error/p_notfound.jsp&lt;/location&gt;
  &lt;/error-page&gt;
  </code></pre>
  
  <p>However, when this page is displayed, Japanese characters are garbled. </p>
  
  <p>The same page (p_notfound.jsp) displays properly if displayed directly or even through the servlet filter.</p>
  
  <p>I tried adding a filter to:</p>
  
  <pre><code>request.setCharacterEncoding("UTF8");
  </code></pre>
  
  <p>But that doesn't help. Any ideas?</p>
