Using the flag in Perl code is a code smell. You can set the flag on any string, and you can clear it on any string. The flag doesn't know where the value comes from and what encoding it originally used. The function is_utf8 is also named incorrectly, as it in fact tells you whether the value uses wide characters representation internally. See #131685 for a related discussion.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
