I highlight limitation of occur. Sorry for bad explaining of problem in
previous posts...

"M-s o" is my most frequent key sequence after "C-s" and "C-x o" ))

But when I need search in a set of files... occur fail.

Yes for single file and NO for multiply files...

What I forget mention that Far file manager make search in all possible 
encodings
in single user request!

For English people this feature may look quite silly but I am sad when see how
my colleges just perform work in Far while I read about coding system, read
Emacs manual and look for answer over Internet for basic feature like
searching...


Currently I think that I need enhanced version of "find/grep" and bind in to
Emacs (which perform search in >>file hierarchy<< in selected set of >>coding 
system<<
at once).

Anyone have suggestions?


I would like to see recursive search in selected coding system as Emacs core
feature without any external dependency... Has it sense to request this feature
at bug-gnu-emacs@gnu.org?
