I think the documentation of `gnus-newsgroup-variables' should
actually be improved and it should describe what
`gnus-summary-make-local-variables' does [1] (or maybe I just didn't
read the doc string carefully enough [2]):

When using this expression...

  (add-to-list 'gnus-newsgroup-variables 'mm-coding-system-priorities)

... `gnus-summary-make-local-variables' sets the global value of
`mm-coding-system-priorities' to nil.  I'd guess nil leads to utf-8
instead of iso-2022-jp in your environment.

Do you get the expected behavior with this expression?

  (add-to-list 'gnus-newsgroup-variables
	       '(mm-coding-system-priorities . global))

(Thank for fixing my commit.)

Bye, Reiner.

| gnus-newsgroup-variables is a variable defined in `gnus-sum'.
| Its value is nil
| 
| Documentation:
| A list of variables that have separate values in different newsgroups.
| A list of newsgroup (summary buffer) local variables, or cons of
| variables and their default expressions to be evalled (when the default
| values are not nil), that should be made global while the summary buffer
| is active.
| 
| Note: The default expressions will be evaluated (using function `eval')
| before assignment to the local variable rather than just assigned to it.
| If the default expression is the symbol `global', that symbol will not
| be evaluated but the global value of the local variable will be used
| instead.
| 
| These variables can be used to set variables in the group parameters
| while still allowing them to affect operations done in other buffers.
| For example:
| 
| (setq gnus-newsgroup-variables
|      '(message-use-followup-to
|        (gnus-visible-headers .
| 	 "^From:\\|^Newsgroups:\\|^Subject:\\|^Date:\\|^To:")))
