I don't visit here much at all anymore, but I have to drop in to say that statement above is far too ignorant. You'll run out of normal text input immediately when you start dealing with stuff like surnames. Take Müller or Selänne. In the internationalized world of today it is not safe to assume 91 characters to be enough for anything.

And in any case whatever code you write you better write it so that unexpected input doesn't crash it. There will always be unexpected input. Some people do unexpected input by purpose. They are called NSA.
