How to correct double-encoded UTF-8 strings sitting in MySQL utf8_general_ci fields?

Question

I have to redesign a class where (amongst other things) UTF-8 strings are double-encoded wrongly:

$string = iconv(\'ISO-8859-1\', \'UTF-8\', $string);
:
$str

MySQL provides a regexp match but no regexp replace, so you're usually better off iterating through each row in php, converting as needed, and updating the row if it has been changed.
