<p> The two octet sequence <c>c2 a3</c> is the [wp://UTF-8] encoding of the pound character, so for Perl to treat it as one single character, you need to <i>decode</i> it: </p>
<c>
use Encode;
my $f = "%C2%A3";
$f =~ s/%([a-fA-F0-9]{2})/pack('C', hex($1))/eg;
my $decoded = decode("UTF-8", $f);
</c>
<p> And then, depending on what you want to do with the decoded string on the output side, you might want to encode it again — usually done via setting the appropriate [doc://PerlIO] encoding layer for the respective file handle. </p>
