title: Convert utf8 without bom to utf 8
body: <h2>Files</h2>
  
  <ul>
  <li><p>index.php :</p>
  
  <pre><code>&lt;?php
  include_once 'index_a.php';
  ?&gt;
  </code></pre></li>
  <li><p>index_a.php :</p>
  
  <pre><code>&lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;test&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          casa
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre></li>
  </ul>
  
  <h2>Results</h2>
  
  <p>The first result is from the <code>index.php</code> and the second <code>index_a.php</code>.</p>

  <p>Why I defend those quotes? </p>
  
  <p>If <code>index_a.php</code> converts the file in UTF-8 without BOM, quotation marks do not appear, but I want the file to be encoded in UTF-8.</p>
