how to unescape strings?

how do you unescape strings and remove the linebreaking characters? using the unescape() method doesn't do anything to strings.

$db = fORMDatabase::retrieve();

$testString = 'foo

bar';

$escaped = $db->escape('string', $testString);

echo $escaped; // 'foo\n\n\n    bar'

// unescaping strings doesn't do anything to the string

$unescaped = $db->unescape('string', $escaped);

echo $unescaped; // 'foo\n\n\n    bar'
