With recent debian i386 perl 5.10.1 and its supplied Scalar::Util 1.21,
the program below prints
str is utf8
dual not utf8
where I hoped the utf8-ness of the given $str might propagate to the
dualvar() result.
use strict;
use warnings;
use Scalar::Util;
print "Scalar::Util $Scalar::Util::VERSION\n";
my $num = 123;
my $str = "\x{262E}";
print utf8::is_utf8($str) ? "str is utf8\n" : "str not utf8\n";
my $dual = Scalar::Util::dualvar ($num, $str);
print "dual n=",$dual+0," s=$dual\n";
print utf8::is_utf8($dual) ? "dual is utf8\n" : "dual not utf8\n";
exit 0;
