title: excel file not generating after UTF-8 encoding chosen
body: <p>This part of my code was creating xls file successfuly   </p>
  
  <pre><code>FileOutputStream fileOut = new FileOutputStream("c:\\Decrypted.xls");
  wb.write(fileOut);
  fileOut.close();
  </code></pre>
  
  <p>when other part of the code had this statement ( which was before the above code )</p>
  
  <pre><code>in = new ByteArrayInputStream(theCell_00.getBytes(""));
  </code></pre>
  
  <p>But when I changed it to </p>
  
  <pre><code>in = new ByteArrayInputStream(theCell_00.getBytes("UTF-8"));
  </code></pre>
  
  <p>this part </p>
  
  <pre><code>FileOutputStream fileOut = new FileOutputStream("c:\\Decrypted.xls");
  wb.write(fileOut);
  fileOut.close();
  </code></pre>
  
  <p>is not generating any xls file anymore.</p>
  
  <p>I need to change the encoding to UTF-8 as I have done in ByteArrayInputStream line, so what should I do that the code still generates xls file. </p>
  
  <p>In case you need it, the two parts are taken from this function. </p>
