From @perlpunk

in the following testcase, length() does not return the correct value (at
least not at the first time).
first it outputs 5 (which is wrong as it has the UTF8 flag set), then
following calls of length return 4.

---snip---

package UTF8Field;
use strict;
use warnings;
use Encode();
use Devel​::Peek;

use overload '""' => 'stringify';

sub new {
  my $class = shift;
  my $new = shift;
  return bless \$new, $class;
}
sub stringify {
  my $self = shift;
  my $str = Encode​::decode("utf8", $$self);
  Dump $str;
  warn "str​: $str l​: " . length($str) ."\n";
  return $str;
}

package main;
use Devel​::Peek;
use strict;
use warnings;
binmode STDOUT, "​:utf8";

my $t = "B\303\266se";

my $u = UTF8Field->new($t);
print length $u, "\n";
print length $u, "\n";

Sorry for the delay. This bug is fixed with change 28006, which I expect will
be merged across into 5.8.9
