Thanks for at least trying. I haven't found anyone else that has been
able to replicate it either, this would be a huge pain to chase down for
me. I'm able to replicate it 100% of the time on my system. So if anyone
IS interested in trying please contact me and I will give them a shell
account to help me figure out what is wrong. The new version of bash
doesn't seem to let me echo unicode properly, so I would be greatly
interested in figuring out what is wrong. Or for some guidance on fixing
that.
