$url = 'http://business.scotsman.com/topics.cfm?format=rss&tid=181';
$rss = fetch_rss($url);
$limit = rand(0,count($rss->items));

foreach($rss->items as $item)
{
      $rss_description = $item['description'];
      $rss_title = $item['title'];
      
      /*
      $rss_title = str_replace('‘',''',$rss_title);                  
      $rss_title = str_replace('’',''',$rss_title);                
      $rss_title = str_replace('‚',',',$rss_title);                
      $rss_title = str_replace('“','"',$rss_title);                
      $rss_title = str_replace('”','"',$rss_title);                
      $rss_title = str_replace('"','"',$rss_title);                                           
      $rss_title = str_replace('¼','¼',$rss_title);                     
      $rss_title = str_replace('½','½',$rss_title);        
      $rss_title = str_replace('¾','¾',$rss_title);
      $rss_title = str_replace("'","'",$rss_title);
      $rss_title = str_replace('—','-',$rss_title);
      $rss_title = str_replace(' — ',' - ',$rss_title);
      $rss_title = str_replace('  ',' ',$rss_title);
      $rss_title = str_replace('£','£',$rss_title);
      */
      
      $rss_title = str_replace('?','£',$rss_title);

I would try using the html_entities or html_special_chars function on $rss_description PRIOR to the str_replaces.

This will ensure that the symbol is in a format that can be 'found' in the str_replace. I've run into this before and that was the solution.
