bug#72077: 30.0.60; customizing which-key-dont-use-unicode to nil results in nil which-key-separator

[Robert Pluim <rpluim@gmail.com>]

mkdir /tmp/emacs-30
HOME=/tmp/emacs-30 src/emacs
M-x which-key-mode
M-x customize-variable which-key-dont-use-unicode RET

toggle it to nil, save it, resulting in the following .emacs:

    ;;; -*- lexical-binding: t -*-
    (custom-set-variables
     ;; custom-set-variables was added by Custom.
     ;; If you edit it by hand, you could mess it up, so be careful.
     ;; Your init file should contain only one such instance.
     ;; If there is more than one, they won't work right.
     '(which-key-dont-use-unicode nil))
    (custom-set-faces
     ;; custom-set-faces was added by Custom.
     ;; If you edit it by hand, you could mess it up, so be careful.
     ;; Your init file should contain only one such instance.
     ;; If there is more than one, they won't work right.
     )
