I'm trying to set this

╭────
│C-x RET r utf-8 RET
╰────

as "C-x zx" as I'm finding that I need to use this block-quoted
command fairly regularly for some unknown reason.

I have set it as

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "C-x zx") 'r utf8)
#+END_SRC
--8<---------------cut here---------------end--------------->8---

but the system rejects it as the "utf8" stage.

How can I set it please?

Thanks
Sharon.
