I answered my own question. It works, but throws warnings if you have them turned on.

$test_hash_ref = {
                   'apple' => 'red',
                   'junk' => 'foo^bar',
                   'junk2' => undef,
                   'lime' => 'green'
                 };

$test_hash_ref = {
                   'apple' => 'red',
                   'junk' => 'foo^bar',
                   'lime' => 'green',
                   'junk2' => ''
                 };
