Hi,

	* gnus-group.el (gnus-update-group-mark-positions):
	* gnus-sum.el (gnus-update-summary-mark-positions):
	* message.el (message-check-news-body-syntax):
	* gnus-msg.el (gnus-debug): Use `string-as-multibyte' to convert
	8-bit unibyte values to a multibyte string for search functions.

Isn't at least the change to gnus-sum.el wrong?  When using
Emacs 22.0.0, there's a problem that we cannot set marks to
articles in the Gnus summary buffer.  For instance:

I realized Gnus searches the unibyte strings "\200", "\201",
"\202" and "\203" in the multibyte buffer named " *gnus work*"
when entering into the summary mode.  Your change made Gnus
search multibyte strings and it fails.  OTOH, Emacs 21.3.50
doesn't fail it as follows:

(with-temp-buffer
  (set-buffer-multibyte t)
  (insert (string-as-unibyte "\200"))
  (goto-char (point-min))
  (search-forward (string-as-multibyte "\200") nil t))
 => 2 (02, 0x2) = ?\C-b

Probably, possible solution will be to withdraw your change or
to use string-as-unibyte.  Please note that you should use
mm-string-as-unibyte instead of string-as-unibyte since Gnus
supports XEmacs as well as Emacs.

Best regards,
