title: PHPExcel fill the accents as false
body: <p>I have a problem with PHPExcel library 1.7.9 creating a xlsx.</p>
  
  <p>Im using fromArray method to fill a MySQL table into an xlsx, when i try to fill any cell with accents, the cell is filled as "FALSE".</p>

  <p>This is my code:</p>
  
  <pre><code>$query="SELECT 
      Caso,
      Etq_Amarilla,
      Tipo,
      Etiqueta,
      'EC Sociedad',
      ProveedorEscalado,
      Proveedor_de_Mantenimiento,
      organizativo,
      OficinaPeople,
      centro,
      sociedad,
      Tipo_Disp,
      Fecha_y_hora_de_creacion,
      Fecha_y_hora_de_cierre,
      domicilio,
      jcentro04,
      analitico,
      DTDT
  from CdM_Diario where Dia='5'";
  
  $datos=$mysqli-&gt;query($query);
  $objPHPExcel-&gt;setActiveSheetIndex(4);
  $objPHPExcel-&gt;getActiveSheet()-&gt;fromArray($cabecera,NULL,"A1");
  $cont=2;
  while($fila=$datos-&gt;fetch_assoc())
  {
      $objPHPExcel-&gt;getActiveSheet()-&gt;fromArray($fila,"pepe","A".$cont."");
      $cont++;
  }
  $cont=2;
  </code></pre>
  
  <p><strong>Solved with:</strong></p>
  
  <p>$mysqli->set_charset('utf8');</p>
