title: Decode html special chars and other elements
body: <p>How to convert in PHP elements like <code>&amp;agrave;</code> and <code>&amp;#8217;</code> to a default utf8 character?</p>
  
  <p>I try html_entity_decode with no success (i display some <code>?</code> in place of the <code>&amp;agrave;</code> and <code>&amp;#8217;</code> in place of <code>&amp;#8217;</code>)</p>
