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
@defun set-process-filter-multibyte process multibyte
This function sets the filter multibyte flag of @var{process}
to @var{multibyte}.
@end defun
@defun process-filter-multibyte-p process
This function returns the filter multibyte flag of @var{process}.
@end defun

decodes the output according to the process output coding system,

* 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.
