Xemacs (Mule) and GNU Emacs, problem with drafts and encoding.

Hello 

I use gnus with both Emacsen. However the drafts which are saved are not
compatible with each other.


According to the documentation"

,----
| 
| `message-draft-coding-system' is a variable declared in Lisp.
|   -- loaded from "message"
| 
| Value: escape-quoted

| Documentation:
| *Coding system to compose mail.
| If you'd like to make it possible to share draft files between XEmacs
| and Emacs, you may use `iso-2022-7bit' for this value at your own risk.
| Note that the coding-system `iso-2022-7bit' isn't suitable to all data.

I tried  that but this coding setting but alas it does not make the
drafts compatible. 

Why does Xemacs not support the utf-8 coding for drafts, although in
general it does support this format?
