utf-8 encoding in DOMDocument class

Question

I am using PHP's DOMDocument class to open an HTML file, make some changes, and save it. The problem is that the javascript in every page that is loaded, contains utf 8 characters, and when I save the HTML file, these characters are "changed". Here's my code.

$doc=new DOMDocument();
$doc->loadHTMLFile($path);

$doc->encoding='UTF-8';
$doc->saveHTMLFile($path);

The file is saved again but the special characters gets distorted. eg if my javascript had an image path set to french/Comment ça s'écrit/ , this becomes french/Comment ça s’écrit  . The wierd thing is that this only happens to my javascript paths, the html elements dont get changed and are in the correct encoding.

Answer 1

try placing your javascript between CDATA tags as shown below

<script type="text/javascript">
/*<![CDATA[*/
    // your javascript here
/*]]>*/
</script>
