Gnus does not convert messages for storage AFAIK.  What are you trying
to accomplish?

I use spam.el with spam-use-bogofilter (bogofilter configured with
unicode=yes and default_charset=utf-8) and I noticed correctly
displayed german umlauts and badly displayed german umlauts in my
bogoutil -d wordlist.db output. So I assumed bogofilter received
messages in different encodings and wanted to stop that to get
a nice and plain bogoutil -d wordlist.db output.

Sorry for bad english.

Yours sincerely,

(I maintain spam.el)

The function that gets the article as a string is

(defun spam-get-article-as-string (article)
  (when (numberp article)
    (with-temp-buffer
      (gnus-request-article-this-buffer
       article
       gnus-newsgroup-name)
      (buffer-string))))

and then that string gets passed to bogofilter:

	  (when (stringp article-string)
	    (with-temp-buffer
	      (insert article-string)
	         (apply 'call-process-region
		     (point-min) (point-max)
		     spam-bogofilter-program
		     nil nil nil switch
		     (if db `("-d" ,db "-v") `("-v")))))))

So spam.el just passes the article as a string, using the
gnus-request-article-this-buffer function.  We can change this if
necessary, to add extra parameters to bogofilter's invocation or to
spam-get-article-as-string to encode to UCS/UTF-8.  I don't know much
about Gnus article encodings so I'm cc-ing this to the ding mailing list
as well in case someone can help.

Ted

p.s. your English is fine :)

How does spam.el handle encrypted messages? Hopefully it
does not feed them into bogofilter :-)
