Coding system in compilation buffer

Coding system in compilation buffer

[Enno Fennema]

I am using GNU Emacs 22.1.1 part of SuSE Linux 10.3 x86_64.
When doing a compile gcc writes its messages/warnings using utf-8 which 
does not help readability when the buffers assumes latin-1.

Trying the get the compilation buffer to accept utf-8 I tried

 >>
(defun compile-utf ()
   "Set compilation buffer for UTF-8"
   ( save-current-buffer
     (set-buffer compilation-buffer)
     (set-buffer-process-coding-system "utf-8" "utf-8")))

(setq compilation-process-setup-function 'compile-utf)
<<

Now doing a compile appears to call the function compile-utf but then 
moans that compilation buffer is a void variable.

That appears to contradict the description of 
compilation-process-setup-function which says that compilation-buffer 
should be bound by the time that function is called.

I am no elisp expert at all and appreciate help.

Does the above idea make sense or is there a better approach?

If the above, then how should I get it to work properly.

Enno Fennema

For me it works to have environment variables LANG and LC_CTYPE set  
some UTF-8 value, not setting a language environment in my user init  
file, but having

	(prefer-coding-system 'utf-8)

Well, on Mac OS X ...

Check also by launching GNU Emacs with -Q, i.e. no customisation  
neither from your system not from you. Last resort might be the  
variable process-coding-system-alist. It *might* be successfully  
manipulated with

	(modify-coding-system-alist 'process "\\*compilation\\*\\'"   'utf-8)
