I found resolution. It looks like it is problem windows locale issue than perl itself.
Running command
chcp utf8
Makes work just fine. Default is 852. I'm very supprised because I use unicode
encoding all the the time and never had such issue. For me it would be better
to detect if codepage is set to 852 and warn user that perl6 may not work well.
Shall we close it or leave defect for future improvement?
