Yes, that's still wrong. In addition to the curly bracket, a slash was also missing. I think this happened while I was writing the post, changing the text and where to break the code a couple of times. Sorry for the confusion, and thanks for pointing it out.
If you are still having trouble with the lesser used letters (q,x,v,p,c,f,z,l,b,h), then it's probably an encoding problem with the umlauts ä,ö,ü. If you don't care about them, you can use these lines:
So, removing the first curly bracket or the slash is obviously not an option to shorten the code :-).
