 This includes the Emacs initialization
 file, @file{.emacs}, and the initialization files of packages
 such as Gnus.  However, you can specify unibyte loading for a
-particular Lisp file, by adding an entry @samp{unibyte: t} in a file
-local variables section (@pxref{File Variables}).  Then that file is
-always loaded as unibyte text.  Note that this does not represent a

-Note also that this feature only applies to @emph{loading} Lisp files
-for evaluation, not to visiting them for editing.  You can also load a
-Lisp file as unibyte, on any one occasion, by typing @kbd{C-x
-@key{RET} c raw-text @key{RET}} immediately before loading it.
