from the manual on DOM,
*Note*: DOM extension uses UTF-8 encoding. Use
utf8_encode()<http://us.php.net/manual/en/function.utf8-encode.php>and
utf8_decode() <http://us.php.net/manual/en/function.utf8-decode.php> to work
with texts in ISO-8859-1 encoding or
Iconv<http://us.php.net/manual/en/ref.iconv.php>for other encodings.
