vim and unicode

[Max Brown]

Hi,

I am having some problems with vim and unicode files.

If I create a file test.txt with some random text in it, then open it
in vim, :set encoding=unicode, and save, then strange things happen:

$ cat test.txt
123
123
max:~ max$ file test.txt
test.txt: ASCII text
max:~ max$ vim test.txt
max:~ max$ file test.txt
test.txt: binary Computer Graphics Metafile

If I now open the text file in vim, there are lots of strange
characters interspersed. The file looks ok in Textedit.

Is this expected behaviour?

Thanks.

Max
