I looked at the man page for this module, and it doesn't give anything past 5.22. So I don't understand how Jim can say they appear to expect to be Unicode 10 conforming. What I think happened is that Unicode 10 made some change that violated the assumptions of this module, and that we should reject this ticket, and make sure one is opened on the module -- Karl Williamson --- via perlbug: queue: perl5 status: open https://rt.perl.org/Ticket/Display.html?id=131810
