Just to add on top of what Abigail-II mentioned (why it is worth to mention "\x00"?).

If Perl, "" and "\x00" are not the same: (for people from c background, this is different in Perl and c.)

use strict;
use warnings;

if ("\x00" eq "") {
    print "they are the same";
} else {
    print "they are not the same";
}

But they are the same in c/c++:

#include <iostream.h>

int main() {
    if (!strcmp("", "\x00")) {
        cout << "they are the same" << endl;
    } else {
        cout << "they are different" << endl;
    }
}
