Sorry for long delay in respond.

Just for info I ask same question at:

http://stackoverflow.com/questions/9290211/look-how-to-search-a-text-in-selected-coding-system-in-files-hierarhy


Personally I found bad about Emacs that it depends on tools which come from
'70 (like find, grep, ls) and work perfectly only with LANG=C.

Two year ago with help from gnu.emacs.help I make Dired independent from
system 'ls' (Cygwin ls use my LANG=cp1251 but Cygwin /etc/passwd always use
UTF-8 so I have wrongly displayed owner filed which broke column indenting):

  ;; If non-nil - use 'insert-directory-program', which I dislike.
  (setq ls-lisp-use-insert-directory-program nil)
  (setq ls-lisp-ignore-case t)
  (setq ls-lisp-dirs-first t)
  (if (memq system-type '(windows-nt cygwin))
      (setq ls-lisp-verbosity nil)
    (setq  ls-lisp-verbosity '(links uid gid)))
  ;; Force use 'ls-lisp-format-time-list'.
  (setq ls-lisp-use-localized-time-format t)
  (setq ls-lisp-format-time-list
        '("%Y-%m-%d %H:%M:%S"
          "%Y-%m-%d %H:%M   "))
  (require 'ls-lisp)


Now time for ))GREP(( independent search... Only with Emacs build-ins...

Emacs must take example from Far manager which have option to perform search
in all codings suitable  for Russian lang (cp866, cp1251, koi8-r, UTF-8).

I can not use Emacs in translation project where I need fix all occurrence of
wrong translation.

What possibilities exist in this filed?
