     function utf8_stripspecials($string,$repl='',$additional=''){
         global $UTF8_SPECIAL_CHARS;
         global $UTF8_SPECIAL_CHARS2;
  
         static $specials = null;
         if(is_null($specials)){

             $specials = preg_quote($UTF8_SPECIAL_CHARS2, '/');
         }
  
         return $string;
         return preg_replace('/['.$additional.'\x00-\x19'.$specials.']/u',$repl,$string);

  What was the input string here, which contained the invalid utf8?

  Judging from the screenshot it seems pretty clear that the bug is in the arctic template... Or do I misinterpret that?

  It's not really clear what get's passed to preg_replace here. The error occurs downwards in cleanID(). The current ID should be 'start' which should not be a problem and has no offset 163, so something else gets passed to cleanID here, whatever that may be. Without additional info that's hard to fix. It seems not occur for any other users so some configuration, template error or file corruption might be the problem here.
  
  Since we got no feedback from the original poster I'll close this.
