HTML special characters changed to foreign characters
It should work in a proper Drupal environment 


  Several people have asked how to specify the character encoding that
  Drupal uses. The short answer is: you can't.


How can I change Drupal's character encoding


  Drupal uses UTF-8 for encoding all its data. This is a Unicode
  encoding, so it can contain data in any language. You no longer need
  to worry about language specific encodings for your website (such as
  Big5, GB2312, Windows-1251 or 1256, ...). Also, when Drupal imports
  external XML data (such as RSS or XML-RPC), it is automatically
  converted into UTF-8 (iconv support for PHP will be required for most
  encodings).
