with UTF-8 setup:

(setq load-path (cons "/usr/share/emacs/site-lisp/mule-ucs" load-path))
(require 'un-define)
(eval-after-load "mm-util"
  '(setq mm-mime-mule-charset-alist
	 (append '((utf-8 cyrillic-iso8859-5 latin-iso8859-1)) mm-mime-mule-charset-alist)))
(setq mm-body-charset-encoding-alist
  '((iso-8859-1 . 8bit)
    (utf-8 . 8bit)
    (koi8-r . 8bit)
    (big5 . 8bit)))

When i try to raw preview a message (C-u M-m P) i get the something like

\320\237\321[  ] \320\277\320\265\321\200\320\260 1 Pr\303\264b\303\241 p\303\250r\303\245 2
where the   ^^^^ is an "Invalid character 013520, 5968, 0x1750" (as reported by C-u M-x =).

The "*Raw MIME preview ...*" buffer is not in raw encoding but in
cyrillic-koi8 (status line contains "-R:%*").

When i try to send a message, i get a warning:
