Before the hacking caused some deleting I had a post here, even though it's an old thread. I'll just repost in a shorter version:
There seems to be some misunderstanding here. In fraktur typefaces there was often used a so called "long s" (Wikipedia has an article on it). In fraktur typefaces this look very simular to an "f" (as do the "k") but it's not the same. However, you need good scans you want OCR to be able to tell the difference.
