Author: Michael Albinus <address@hidden>
Commit: Michael Albinus <address@hidden>

    Fix coding system for Tramp on OS X.
    
    * lisp/net/tramp-compat.el: Require ucs-normalize.
    
    * lisp/net/tramp-sh.el (tramp-open-connection-setup-interactive-shell):
    Set coding system to `utf-8-hfs' for Mac OS X.
    
    * test/automated/tramp-tests.el (tramp-test29-vc-registered):
    Flush directory properties when needed.
    (tramp--test-utf8): Include Chinese file name, again.
