It includes two percent characters.  Here is the value used:

(#("Gnus: d.t.utf8-æøå [ h   e] Re: Test path with %%" 0 5
   (help-echo "This is Gnus" display
              (image :type xbm :file 
"/home/user_2/abraham/linux/share/emacs/21.1/etc/gnus-pointer.xbm" :ascent 
center))
   5 20 nil 20 21
   (help-echo "All citation text visible")
   21 22
   (help-echo "Hidden headers")
   22 23
   (help-echo "No hidden encryption nor digital signature status")
   23 24
   (help-echo "Signature is visible")
   24 25
   (help-echo "No overstrike characters applied")
   25 26
   (help-echo "/*_Emphasis_*/ characters applied")
   26 49 nil))

I get this by evaluating the call to
'gnus-mode-line-buffer-identification' below:

      (setq mode-line-buffer-identification
            (gnus-mode-line-buffer-identification (list mode-string)))
      (set-buffer-modified-p t))))

I tried 

    (setq mode-line-buffer-identification '("foo%%"))

which works fine, I get "foo%" in the mode line as expected.
