I use the copy/duplicate feature a lot and since i have done the upgrade when I try to copy or duplicate a product the name is the Only thing that actually copies over. this is the only last thing that has shown up in my console and i recopied the collect_info.php file over from the original

[26-Aug-2012 09:45:05] PHP Warning: htmlspecialchars() [function.htmlspecialchars]: Invalid multibyte sequence in argument in /home/user/mysite/myrenamed-admin/includes/modules/product/collect_info.php on line 401
not sure if the two were related but putting the new collect_info.php file didn't fix my copying over problem.

any one know the fix to this.
