I advise you to update to perl 5.8.0, because I have noticed similar errors between utf and other charset conversions/comparisions functions in perl 5.6.1. Some things just don't seem to work as expected. I'm not an utf or perl expert, but 5.8.0 seems to be more consistent, so if you have to do a lot of utf/charset relevant things...
