I cannot reproduce this with a recent Emacs 24.3.50.

This looks suspicious. What is the name of the file in question? What is
the whole path to that file? Are there any non-ASCII characters?

There have been some recent changes in Tramp, which allow better support
of utf8. Maybe that fixes this already.

However, first I would like to reproduce the problem with Emacs 24.3.
