MS IE and RSS and International?

The XML parser in IE is less than impressive when dealing with characters with an accent. It came to my attention recently that my feed wasn't not working. After looking into the error, it so happens I had written the word "cliche" the proper way, ie with an accent on the e. The XML parser in IE was barking on it, and saying it's an illegal character... It's not. FireBird on the other end is working just fine. BTW my feed, since I've changed a few times in the last few weeks is xml feed
