vc-version-other-window, does not "respect" UTF-8

[Uwe Brauer]

Hello

Starting xemacs-21.4.19 mule -vanilla with the minimal lines of my
last post, in order to use utf-8, I observed the follwing.

I created a file test in which I wrote some lines in spanish
input spanish-prefix, I saved it in utf-8 and registered the file
under vc (RCS). I checked in added some more text, checked out.

The command 
        file test 
tells me 
        test: UTF-8 Unicode text

Now I use vc-version-other-window but then 
file test.~1.3~
test.~1.3~: ISO-8859 text, with no line terminators

So the file is not in UTF-8. That is really bad. 

Can anybody reproduce this? What shall I do?


thanks
