RSS Feed Sydication Program & Wordpress Feed Character Problems

[cebuy]

Problem I am having is that a feed I pull off of my Wordpress blogs is getting dumb characters in the html output using this script I use.  For example... I am trying to take and use the rss feed at http://www.GeraldineAlabama.com/news/feed  to post to http://www.GeraldineAlabama.com home page as news.  I am using a free third party script called RSS Fetch 0.4.3 found at

www.neoprogrammers.com  It has worked fine on news feeds for most part but on the Wordpress Blog Feeds it seems to insert characters like  and € and I dont want it to be messed up like . Here is code... Is there something I can do make sure this does not happen???  Anyone like to fix this for me?  I can code some but I am very very green.  THanks!
