[hunchentoot-devel] error computing the request object

Hello, Im using utf-u as the default external format in my web application (yet another social news site). Some sites have started to add links to our site, passing the title of their news as a GET parameter in the link. The problem is that one of those sites is encoding the title string using iso-8859 encoding, which causes hunchentoot to return a "Your browser sent a request that this server could not understand." and a log error that looks like "Error when creating REQUEST object: Unexpected value #x20 in UTF-8 sequence.".

Is there a way I can catch the error so that I can either to ignore the parameters or try to recompute the REQUEST object using iso-8859 encoding?

Thanks Sergio
