I guess your buffer-file-coding-system is neither 'undecided' nor
anything that can encode the curved quotes.  Try

  C-x RET f utf-8 RET

and then type the above again.

Paul, I think this condition:

  (defun electric--insertable-p (string)
    (or (not buffer-file-coding-system)
        (eq (coding-system-base buffer-file-coding-system) 'undecided)
        (not (unencodable-char-position nil nil buffer-file-coding-system
                                        nil string))))

should also accept a coding-system that is the default-value of
buffer-file-coding-system, because that's how buffers are created.
When the file is saved, Emacs will ask for a proper encoding, which is
not a catastrophe.
