  by listing each of the characters within the square brackets that
  delimit the vector.
+   Language and encoding settings can be a reason for failing key
+ binding.  For instance, say you have put the following in your init
+ file:
+ @example
+ (global-set-key [?\M-ö] 'shell)
+ @end example
+ @noindent
+ Now it can happen that the ö character read from the keyboard is
+ actually different from the ö character read from your init file, even
+ though they look the same.  In this case, Emacs will not do what you
+ intended.  First you should check whether they are the same or
+ different.  In the above example, you would position point (the cursor)
+ on the ö character and hit @kbd{C-u C-x =} (the @kbd{C-u} part is
+ important).  The second line of the output will contain the charset.
+ Now hit the ö key and position point on the character thus produced.
+ Again, hit @kbd{C-u C-x =}.  If the two charsets are different, then you
+ have found the problem.  The solution involves putting a `coding cookie'
+ in your init file, @pxref{File Variables}.  For example, suppose that
+ the ö character from the init file has charset latin-iso8859-1 whereas
+ the ö character from the keyboard has charset latin-iso8859-15.  The
+ solution is to put a coding cookie into the first line of the
+ @file{.emacs} file, as follows:
+ @example
+ ;; -*- coding: iso8859-15; -*-
+ @end example
+ @noindent
+ @xref{Non-ASCII Rebinding}, if the charset printed by @kbd{C-u C-x =} is
+ `eight-bit-graphic'.
+   If the variable @code{keyboard-coding-system} is nil, it is probably
+ best to set it to the right value, according to the locale you work in.
