David, you're referring to the letter "ß," otherwise known as Eszett. It functions the same way as "ss" (or "sz") and used to be very common in German place names. You can learn more about it at http://en.wikipedia.org/wiki/%C3%9F.
Yes, I am referring to that letter. I do not even have that on my keyboard here. I was making people aware of it, in case they wanted to look up Großfahner. I did not know that it was called Eszett. thanks for the added input.
