Re^5: system function not handling string properly

Normal Data::Dumper returns

$VAR1 = 'www.youtube.com/watch?v=mark';
[download]

but after setting

$Data::Dumper::Useqq = 1;
[download]

I get

$VAR1 = "w\0w\0w\0.\0y\0o\0u\0t\0u\0b\0e\0.\0c\0o\0m\0/\0w\0a\0t\0c\0h
+\0?\0v\0=\0m\0a\0r\0k\0";
[download]

To get the correct output, I have to

use Encode;
$link = decode('utf-16-le', $link);
[download]

Thank you. That is really interesting. Good finding! I'm really curious why Data::Dumper doesn't show the 0-bytes? Best regards McA	[reply]

I'm really curious why Data::Dumper doesn't show the 0-bytes? It does :) its your browser/editor/shell that doesn't actually display them (non-printable), and in some cases doesn't actually copy/paste them Data::Dump does useqq-type-deal by default, and in a step of brilliance exports a dd kinda like this one `sub dd { use Data::Dumper; print Data::Dumper->new([@_])->Sortkeys(1) ->Indent(1)->Useqq(1)->Dump . "\n"; }` [download] I'm really tired of typing `print Dumper();... say Dumper()...` so nowadays I have -MData::Dump=dd,pp in my PERL5OPT	[reply] [d/l] [select]

Thanks alot! I guess I need to brush up on my knowledge of encoding (and Data::Dumper for that matter).	[reply]
