The reason is simple.  OSX uses a less common formatting for umlauts.
Instead of the code for the character ü it represents it as two
characters, one for u and one for the dots.  (Yes, that is still valid
Unicode.)

In fact, if you type "ru", Emacs and Bash will both offer rückerstattung as a
completion.

That being said, I don't know any solution.  I thought utf8-m.el would
fix it, but I must have been mistaken.  It's one of the cases where
UTF-8 isn't backwards compatible with ASCII when comparing strings, so
the fix is non-trivial.
