| Subject: | Corrupts data in perl 5.22 |
======================
use utf8;
use Data::Dumper;
use Data::Dump;
my $data = { x => 'infтест' };
print Dumper $data;
Data::Dump::dump($data);
print Dumper $data;
print $Data::Dump::VERSION, "\n";
print $^V, "\n";
=======================
$VAR1 = {
'x' => "inf\x{442}\x{435}\x{441}\x{442}"
};
{ x => "inf\xD1\x82\xD0\xB5\xD1\x81\xD1\x82" }
$VAR1 = {
'x' => 'infтест'
};
1.23
v5.22.1
note, that it's reproducible only if string starts with "inf", which is funny,yes.
this is per 5.22 from Ubuntu 16.04 LTS
