It's not so much that you aren't able to generate a string or detect the null, it is more likely that things go awry in subsequent processing. Consider:

use strict;
use warnings;

my @strs = ("filename1.txt\0", "filename2\0.txt", "filename3.txt");

/\0/ && ((print "Null char detected in >$_<"), print "\n") for @strs;

Prints:

Null char detected in >filename1.txt
Null char detected in >filename2

Note that print has truncated the strings at the null character. A sign that C is at work under the hood.
