ispell with ngerman and Umlaute öäü

Problem: My ispell with ngerman package recognizes words with an Umlaut like hinüber as two words hin and ber and doesn't even sense the Umlaut

Solution: Check the coding system of the checked file. Ngerman Ispell should work on Files with ISO-8859-15 encoding. (Emacs Command: C-x RET r or M-x revert-buffer-with-coding-system to change the current buffers encoding)
