  emacs20.2から、grepやmgを使って漢字の単語などを検索するにはどうすれ
ば良いのでしょうか? grepでeucのfile中の漢字を検索することもできていま
せん。(emacs19.34では問題なくできています。)

  なおmgは、grepのような機能を持つperl scriptで、-j jisなどと指定する
と、jisコードのfile中の漢字を検索することができます。
  mgに呼出しには以下の関数を使っています。
(defun mg (command-args)
  "Run mg instead of grep."
  (require 'compile)
  (interactive
   (list (read-from-minibuffer "Run mg (like this): "
                               "mg -n " nil nil 'grep-history)))
  (compile-internal (concat command-args " " grep-null-device)
                    "No more mg hits" "mg"
                    ;; Give it a simpler regexp to match.
                    nil grep-regexp-alist))

  以下は、*scratch* bufferからdescribe-coding-systemをやった結果です。
----- begin of describe-coding-system output -----
Coding system for saving this buffer:
  Not set locally, use the default.
Default coding system (for new files):
  E -- euc-japan (alias of japanese-iso-8bit)
Coding system for keyboard input:
  nil
Coding system for terminal output:
  E -- euc-japan (alias of japanese-iso-8bit)
Defaults for subprocess I/O:
  decoding: E -- euc-japan (alias of japanese-iso-8bit)
  encoding: E -- euc-japan (alias of japanese-iso-8bit)

Priority order for recognizing coding systems when reading files:
  1. iso-2022-7bit
  2. japanese-iso-8bit (alias: euc-jp euc-japan euc-japan-1990)
  3. japanese-shift-jis (alias: sjis shift_jis)
  4. iso-latin-1 (alias: ctext latin-1 iso-8859-1)
  5. iso-2022-7bit-lock (alias: iso-2022-int-1)
  6. emacs-mule
  7. raw-text
  8. chinese-big5 (alias: cn-big5 big5)
  9. no-conversion (alias: binary)

  Other coding systems cannot be distinguished automatically
  from these, and therefore cannot be recognized automatically
  with the present coding system priorities.

  The followings are decoded correctly but recognized as iso-2022-7bit:
    iso-2022-jp

  The followings are decoded correctly but recognized as iso-2022-7bit-lock:
    iso-2022-7bit-ss2 iso-2022-7bit-lock-ss2 chinese-iso-7bit korean-iso-7bit-lock

Particular coding systems specified for certain file names:
