I wrote this a while ago... hope it helps.. you can use it as a package or just copy the sub.. 
package Escape;
use Exporter;
# simple escape module for html stuff
# use Escape;
# my $data = escape($string_to_escape);
@ISA         = qw(Exporter);
@EXPORT      = qw(escape);

sub escape {
my $data = shift;
$data =~ s/\%/%25/g;$data =~ s/\t/%9/g;$data =~ s/\n/A/g;
$data =~ s/ /%20/g;$data =~ s/\!/%21/g;$data =~ s/\"/22/g;
$data =~ s/\#/%23/g;$data =~ s/\$/24/g;$data =~ s/\&/%26/g;
$data =~ s/\'/%27/g;$data =~ s/\(/%28/g;$data =~ s/\)/%29/g;
$data =~ s/\*/%2A/g;$data =~ s/\+/%2B/g;$data =~ s/\,/%2C/g;
$data =~ s/\-/%2D/g;$data =~ s/\./%2E/g;$data =~ s/\//%2F/g;
$data =~ s/\:/%3A/g;$data =~ s/\;/%3B/g;$data =~ s/\</%3C/g;
$data =~ s/\=/%3D/g;$data =~ s/\>/%3E/g;$data =~ s/\?/%3F/g;
$data =~ s/\@/%40/g;$data =~ s/\[/%5B/g;$data =~ s/\\/%5C/g;
$data =~ s/\]/%5D/g;$data =~ s/\^/%5E/g;$data =~ s/\_/%5F/g;
$data =~ s/\`/%60/g;$data =~ s/\{/%7B/g;$data =~ s/\|/%7C/g;
$data =~ s/\}/%7D/g;$data =~ s/\~/%7E/g;
return $data;
}
