I'm supprised no one has suggested a more complex range, try something like this:

$startCh = chr(0);
$midstopCh = chr(9);
$midstartCh = chr(11);
$endCh = chr(31);

$text =~ s/[$startCh-$midstopCh,$midstartCh-$endCh]//g;

which should work just fine, although I haven't tested it for speed. You can jsut keep specifing more ranges for those chars you wish to exclude, although it becomes rather clunky looking if you have a large number of ranges.
