Title: Prevent errors due to incompatible characters while creating RSS Feed

When you put utf-8 encoded strings in a XML document you should remember that not all utf-8 valid chars are accepted in a XML document http://www.w3.org/TR/REC-xml/#charsets

So you should strip away the unwanted chars, else you’ll have an XML fatal parsing error.
