 @cindex process filter multibyte flag
   When Emacs calls a process filter function, it provides the process
 output as a multibyte string or as a unibyte string according to the
-process's filter multibyte flag.  If the flag is non-@code{nil}, Emacs
-decodes the output according to the process output coding system to
-produce a multibyte string, and passes that to the process.  If the
-flag is @code{nil}, Emacs puts the output into a unibyte string, with
-no decoding, and passes that.
-
-  When you create a process, the filter multibyte flag takes its
-initial value from @code{default-enable-multibyte-characters}.  If you
-want to change the flag later on, use
-@code{set-process-filter-multibyte}.

 * Incompatible Lisp Changes in Emacs 23.1
 
+** The multibyteness of process filters is determined by the coding-system
+used for decoding.  The functions `process-filter-multibyte-p' and
+`set-process-filter-multibyte' are obsolete.

 ** The behavior of map-char-table has changed.  It may call the
 specified function with a cons (FROM . TO) as a key if characters in
 that range have the same value.
