title: UTF-8 Char are not displaying in TableViewer SWT
body: <p>I created TableViewer in that I'm setting table item text as following.</p>
  
  <pre><code>item.setText(0, String.valueOf((char) 255));
  </code></pre>
  
  <p>After running the program there is nothing displaying for above.</p>
  
  <p>If I create <code>org.eclipse.swt.widgets.Text</code> or <code>org.eclipse.swt.widgets.StyledText</code> and set that value then I'm getting <code>ÿ</code> </p>
  
  <pre><code>StyledText styledText = new StyledText(shell, SWT.BORDER);
  styledText.setText("Hello " + String.valueOf((char) 255));
  </code></pre>
  
  <p>I tried to set <code>StyledCellLabelProvider</code> but still no value is showing for  <code>String.valueOf((char) 255)</code>       </p>
  
  <p>I tried to run the application with <code>-Dfile.encoding=utf-8</code> option but no help.  </p>
  
  <p>What I'm missing here?, why table not displaying UTF-8 char</p>
