Problem with coding system and emacsclient

Problem with coding system and emacsclient

[Juraj Kubelka]

Hi!

I have problem with opening files with emacsclient in different
coding.

My default coding system is:

------- M-x describe-coding-system RET RET
Coding system for saving this buffer:
  2 -- iso-8859-2 (alias of iso-latin-2)
Default coding system (for new files):
  2 -- iso-8859-2 (alias of iso-latin-2)
Coding system for keyboard input:
  nil
Coding system for terminal output:
  2 -- iso-8859-2 (alias of iso-latin-2)
Defaults for subprocess I/O:
  decoding: 2 -- iso-8859-2 (alias of iso-latin-2)
  encoding: 2 -- iso-8859-2 (alias of iso-latin-2)

Priority order for recognizing coding systems when reading files:
  1. iso-8859-2 (alias of iso-latin-2)
  2. iso-latin-1 (alias: iso-8859-1 latin-1)
  3. iso-2022-jp (alias: junet)
  4. iso-2022-7bit 
  5. iso-2022-7bit-lock (alias: iso-2022-int-1)
  6. iso-2022-8bit-ss2 
  7. emacs-mule 
  8. raw-text 
  9. japanese-shift-jis (alias: shift_jis sjis)
  10. chinese-big5 (alias: big5 cn-big5)
  11. no-conversion (alias: binary)
  12. mule-utf-8 (alias: utf-8)
-------

I can open file with coding system cp1250:

C-x RET c cp1250-unix RET C-x C-f file_coding.txt

Everything is correct. Now I save and close file.

I can open file again with same sequence above. But when I want open
file with emacsclient I cannot use prefix "C-x RET c cp1250-unix RET"
and file is opened in "Unibyte raw-coding".

------- M-x describe-coding-system RET RET
Coding system for saving this buffer:
  t -- raw-text
-------

Characters are strange of course. I can use "C-x RET f cp1250-unix
RET" and file is now opened in "Unibyte cp1250-unix". 

------- M-x describe-coding-system RET RET
Coding system for saving this buffer:
  D -- cp1250-unix
-------

But old text is still displayed strange. And new characters added to
file are strange too. 

Do you have any solution for it? How open file in different coding with
emacsclient (I know coding of file)?

Thanks.

Jura

Unfortunately I am right now doomed to work on the operating system
that dare not say its name; I can't make any test with emacsclient.
So I am probably not the right person to answer your question right
now. However, since nobody else has replied so far, I might as well
try my best.

When the character encoding scheme has not been properly detected on
visiting the file, then it's too late to do `C-x RET f'. Recent CVS
Emacs provides the command 
`C-x RET r' (`revert-buffer-with-coding-system') which, erm, reverts
the buffer with a different coding system.

It would be nice, if emacsclient had some sort of --encoding option to
specify the encoding on the command line (but maybe it does? Have you
checked?). Failing that I can think of two ways to get what you want:

The best way is probably to put a coding system cookie into the file:

At the beginning:


-*- coding: windows-1250 -*-


At the end:


Local Variables:
coding: windows-1250
End:


See (info "(emacs)Recognize Coding").


Another way would be to frob the coding system priorities:

;; Move windows-1250 (aka cp1250) to front.
(prefer-coding-system 'windows-1250)

;; Move Latin-2 to front again, because that's what is actually
;; prefered.
(prefer-coding-system 'iso-latin-2)

In Emacs 21.3 you can get the same effect with `C-x RET c whatever RET
C-x C-v RET'.

Thank you very much, prefer-coding-system and `C-x RET c whatever RET
C-x C-v RET' are what I need.
