*** The command C-x RET p (set-buffer-process-coding-system)<BR>
specifies the coding system for input and output to a subprocess.
This command applies to the current buffer; normally, each subprocess
has its own buffer, and thus you can use this command to specify
translation to and from a particular subprocess by giving the command
in the corresponding buffer.
<P>
By default, process input and output are not translated at all.
