Comment 1 for bug 537730

Thanks for reporting bugs with Kupfer, encoding bugs are important.

I can't reproduce something exactly like that here. However the traceback suggests that the error comes from the *alias* of a program, and what I can see in the code these aliases are not handled correctly with respect to filesystem (filename) encoding. So I have a proposed fix for that problem, I hope that this solves it for you:
