I did this change:

@@ -609,6 +610,7 @@ mm-find-mime-charset-region
     (if (and (memq 'iso-2022-jp-2 charsets)
 	     (memq 'iso-2022-jp-2 hack-charsets))
 	(setq charsets (delq 'iso-2022-jp charsets)))
+    (message (format "mm-util.el:mm-find-mime-charset-region b:%s e:%s f-c-s-r: %s return:%s" b e (find-coding-systems-region b e) charsets))
     charsets))
 
 (defmacro mm-with-unibyte-buffer (&rest forms)

and then did S D r on the feedbase-email¹. In *Messages* I got:

Then I tried on my original article in this thread² (the one you tested
with), and I got:

  Sending via mail...

So it looks like it is calling find-mime-charset-region on each header
in the second case and not on the body, but in the failing case, it
calls it on the body only?!


  Still puzzled,
