No but it worked, and was the first attempt I made to get it to work.
Maybe the values being passed are wrong, or we are getting sign extension?

I believe it is a UTF patch, I googled for perl and UTF8 and found a few
references to this bug in other scripts, and there is reference to
Redhat using an unreleased patch.
