body: <p>I try to build video streaming server using spring framework.</p>
  
  <p>however, always sending get method like this  </p>
  
  <pre><code>"http://localhost:8080/resources/%E2%81%A9mov_bbb.mp4" 
  </code></pre>
  
  <p>file name is mov_bbb.mp4</p>
  
  <p>how come this happened?
  what is %E2%81%A9?</p>
  
  <pre><code>@RequestMapping(value = "/streamView", method = RequestMethod.GET)
  
  @Override
  protected void renderMergedOutputModel(Map&lt;String, Object&gt; model, HttpServletRequest request,
          HttpServletResponse response) throws Exception {
      File file = new File("/resources/mov_bbb.mp4");
      RandomAccessFile randomFile = new RandomAccessFile(file, "r");
  </code></pre>
