inserting them in unibyte buffers converts them to unibyte
automatically. However, if this does make a difference, you can force
a particular Lisp file to be interpreted as unibyte by writing
-@samp{-*-unibyte: t;-*-} in a comment on the file's first line. With
+@samp{unibyte: t} in a local variables section. With
that designator, the file will unconditionally be interpreted as
unibyte, even in an ordinary multibyte Emacs session. This can matter
when making keybindings to non-@acronym{ASCII} characters written as
