Puh, it's lot's of possibilities to choose of, now... I thought 
of something like the foreach-loop but wasn't sure if that is 
correct for all utf encodings. All in all, I think I take the 
any-approach, because it feels a little bit more like looking at 
the string at a whole and I like to use enforce.

Thanks for all your answers!
