> StringHelper#stringDifference does not take supplementary characters into account. Since
this is not used internally at all we should think about removing it but I guess since it
is not too complex we should just or fix it for bwcompat reasons. For released versions we
should really fix it since folks might use it though. For trunk we could just drop it.
