Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This is most probably not a bug; but needs some input from an expert.
In Section 57.6.5 of the Emacs manual (Non-ASCII Characters in Init Files) it is stated
that to use non-ASCII characters the init file must start with a line of the form:
-*-coding: <coding system name> -*-

I tried that with coding system equal to utf-8 and got the following error:

Debugger entered--Lisp error: (void-variable \337-*-coding:)
  eval-buffer(#<buffer   *load*> nil "c:/Documents and Settings/Bostjan/My Documents/.emacs.d/init.el" nil t)  ;  Reading at buffer position 12
  load-with-code-conversion("c:/Documents and Settings/Bostjan/My Documents/.emacs.d/init.el" "c:/Documents and Settings/Bostjan/My Documents/.emacs.d/init.el" t t)
  load("c:/Documents and Settings/Bostjan/My Documents/.emacs.d/init" t t)
  #[nil ^H\205\276^@  \306=\203^Q^@\307^H\310Q\202A^@ \311=\2033 etc.


When I replaced the first line as described above with the following three
lines at the end

;; Local Variables: **
;; coding:utf-8 **
;; End: **


I got a different error:

Debugger entered--Lisp error: (error "Invalid modifier in a string") etc.

any advice would be appreciated

Bostjan

If Emacs crashed, and you have the Emacs process in the gdb debugger,

    `bt full' and `xbacktrace'.

bug#1456: Cannot Put Non-ASCII Characters in Init Files

[Glenn Morris]

See for example the files buff-menu.el and ibuffer.el in the Emacs
distribution (you can use M-x locate-library) for the two ways to
specify coding. Don't forget it must be a comment line in the "first
line in file" method.

Beyond that, any problem may be specific to your init file. Start with
an empty one and see that works. Then remove a half at a time from the
real file until you narrow down the problem. Starting with
"--debug-init" can also help.

Did you manage to track down the problem?

Thanks for your answer. 
I hope I now understand the problem. Actually, I already sent a reply to one
comment message, but since I did not cc it to 1456@emacsbugs.donarmstrong.com,
I am doing so now.

It turned out that of the two problems described in my original bug report, the first
(-*-coding: utf-8-*- in my init file did not work) resulted from not prefixing 
"-*-coding: utf-8-*-" with ";;". 

The second (error "Invalid modifier in a string") was the result of some key redefinitions,
which apparently do not work, or do not work as I thought they would. My original desire
was to provide encodings for some Central European characters that are located in certain
places on the local keyboard. Specifically, they correspond to the US keys ; : ' " [ { ] }
\ | . Therefore, I placed the following code in my init file:

(global-set-key "\C-c;" 'insertch)    ;OK
(global-set-key "\C-c:" 'insertCh)    ;OK
(global-set-key "\C-c'" 'inserttj)    ;OK
(global-set-key "\C-c\"" 'insertTj)    ;OK
(global-set-key "\C-c]" 'insertdj)
(global-set-key "\C-c}" 'insertDj)    ;OK
(global-set-key "\C-c[" 'insertsh)
(global-set-key "\C-c{" 'insertSh)    ;OK
(global-set-key "\C-c\\" 'insertzh)
(global-set-key "\C-c|" 'insertZh)    ;OK

where 'insertch etc. are functions for inserting the appropriate characters. After some
investigation I discovered that one or more of these redefinitions are the cause of
the "Invalid modifier in a string" error. Not wishing to pursue the matter further I simply
took the advice in the manual to accept as user-defined key shortcuts the key sequences
C-c<letter>. After choosing key definitions of that type, my problems went away.
