utf8 wrongly encoded chars in draft messages

Hello

I am using Ma Gnus v0.10 with Xemacs 21.5.34 Mule without problems.

Now I started to use GNU Emacs 24 with gnus as well, and since I started
I have problems with the coding in the draft message for example I see
symbols like

¡

Which I can decode via   (decode-coding-region start end 'utf-8 nil))

To the correct 

¡ 

However when I use C-c C-d the coding is again wrong.

I am not sure who is here the culprit. I tried to play around with 
(setq message-draft-coding-system 'utf8)

But this did not help. Any help is welcome.


thanks
