Hello shilo,

As an aid to debugging, you can configure Data::Dumper to print whitespace characters (other than spaces) as backslash sequences by setting the $Data::Dumper::Useqq configuration variable:

18:58 >perl -MData::Dumper -wE "my $s = qq[\tabc\r\n]; print Dumper($s
+); $Data::Dumper::Useqq = 1; print Dumper($s);"
$VAR1 = '       abc
';
$VAR1 = "\tabc\r\n";

But I generally prefer Data::Dump, which does this by default:

18:58 >perl -MData::Dump -wE "my $s = qq[\tabc\r\n]; dd $s;"
"\tabc\r\n"

Hope that helps,
