I assume you are using Vim in a terminal window.  Did you try if the GUI
(gvim) displays the text correctly?

This works fine for me (in xterm 158).  It looks like for you a second
byte in the range 0x80 - 0x9f is causing trouble.  I can't guess what
could be different in your enviroment that causes this.

I would expect either none of the non-ASCII characters to work or all of
them.  Strange.  Did you check the options 'encoding' (should be
"utf-8") and 'termencoding' (should be empty)?

I assume you are not talking about Vim here.
