Thanks for the report. As shown below, I can't reproduce the bug with grep 2.20 (the current version) in either the en_US.utf8 or the de_DE.utf8 locales. grep 2.5.1a is pretty old (dated 2004) and several bugs have been fixed in this area in the last ten years, so I suggest upgrading and I'm taking the liberty of marking this as done.
$ cat testfile A Ä $ grep -F -eÄ -eA testfile A Ä $ grep -i -eÄ -eA testfile A Ä $ grep -iF -eÄ -eA testfile A Ä
