title: Issue with the character: ' (single quotation) when trying to save to mySql
body: <p>When ever there is this character in a string I try to save: ' (single quotation) - it does not save. No error is generated. I need help to understand what is wrong. My character set must accomodate French characters. Otherwise everything works well.</p>
  
  <pre><code>&lt;?php
  header ('Content-type: text/html; charset=utf-8');

  mysql_set_charset("utf8");

  $contenu  = $_POST['editabledata'];
  $name  = $_POST['name'];
  
  mysql_query("
  UPDATE al_articles SET $name='$contenu'
  WHERE (ArticleID='$articleid')
  
  ") or die(mysql_error());
