I installed the latest Emacs trunk and did some tests with a
message written in Japanese.

1.
(setq mm-coding-system-priorities '(utf8)) is ok.  Messages to
be sent don't seem to be labeled with charset=utf8 .
(setq mm-coding-system-priorities nil) is ok, too.

2.
Type `C-c C-m p text/plain RET' in the message buffer and add
charset=utf8 manually as follows:

< #part type="text/plain" disposition=inline charset=utf8>

In this case the message will be sent with charset=utf8 .
By this result I got to think the system-wide utf8 alias might
be harmful.  The utf8 alias is needed only for reading wrong
configured messages, isn't it?  If so, I think it is enough
using `gnus-summary-show-article-charset-alist'.

cf. (info "(gnus)Paging the Article")

Note that adding (utf8 . utf-8) to `mm-charset-synonym-alist'
causes the same problem (I verified it with Emacs 22.3).
