Thank you!

The double q (qq) worked!

Sorry for the basic question, I'm just starting out with Perl. :-)

    Nonsense. The single quote you originally posted works just as well. 
    my $s = q[<IL.Check/>];
my $r = q[<&#x221a;>];

print "Old word: $s\n";
$s =~ s/$s/$r/;
print "New word: $s\n";

    There's no interpolation or escape sequences here. q vs qq is moot.

    The real problem is that you are using text as a regex pattern without first converting it to a regex pattern. ("#" is special under "x".) Use quotemeta or its alias \Q..\E: 

    my $s = q[<IL.Check/>];
my $r = q[<&#x221a;>];

print "Old word: $s\n";
$s =~ s/\Q$s\E/$r/;
print "New word: $s\n";
