Why don't you use quotemeta ?

Code below 

use strict;
use warnings;

my $sentence = 'The quick brown fox jumped over the lazy dog';
print "$sentence \n";

my $substring = 'The quick.!*?fox';
print "$substring \n";

my $quoted_substring = quotemeta($substring);
print "$quoted_substring \n";

$sentence =~ s/quick brown/$quoted_substring/;
print "$sentence \n";
