これで表示されるようになりました。ありがとうございます。ついでにシフト
JISも使えるようにしようと思い、下のようなCCLを書いています(勝手がわか

バグしてください。_o_

;; newjis.el - support for new JIS (JIS X 0213-1999 Plane 1, 2)
;; Copyright (C) 1998 ITO Takayuki.

;; CAUTION:
;;
;; The standard is currently being reviewed. Not yet fixed.
;; Do not use the standard and this code for practical purposes.
;;
;; The standard name JISX0213, published year 1999,
;; and final characters ?O and ?P are nothing but prediction.
;; EUC and Shift-JIS encodings are also draft proposal.
;; When the formal standard is published they may change.
;;
;; CCL routines for Shift-JIS assume lc-jp3 == 251 and lc-jp4 == 252.
;; If you have already defined other 2-byte 2-column private character sets,
;; you need to change these hard-coded values.

;; BUGS:
;;
;; This elisp code is of alpha quality. Not yet tested thoroughly.
;;
;; EUC file may be recognized as *euc-japan* even though explicitly
;; specified as *euc-japan-new* in reading.
;;
;; SJIS(CR/LF) file may be recognized as *sjis-new*unix even though
;; explicitly specified as *sjis-new*dos in reading.
;;
;; A few ASCII characters may drop in writing SJIS file.
