これは割合簡単にいった。.emacs内で次の指定をすればよい。
'(default ((t (:family "BIZ UDMincho" :foundry "MRSW" :slant normal :weight regular :height 120 :width normal)))))
参考までに、ぼくの.emacsは次のようになっている。
(set-language-environment "Japanese")
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(current-language-environment "Japanese"))
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
