Subject: bug#65993: 29.1; emoji-insert show nothing without font settings
Date: Fri, 15 Sep 2023 21:06:18 +0900

Without font settings, almost all emojis are not displayed within emacs,
and emoji-insert does not show any leaf menu items.
For example, typing 'C-x 8 e e s s' (Emoji > Smileys > smiling)
emacs shows empty minibuffer(no string shown).

In such situation I can not understand what is going on.
Empty menu should show some information or raise an error.

And once emoji-insert is called before font setting,
emoji-insert does not show emoji items after they are made visible in
emacs buffer with font settings.

Here is a sample setting to display emojis:
  (set-fontset-font nil '(#x1f000 . #x1faff) "Segoe UI Emoji")
Without font settings, characters in the range are displayed with
  'Segoe UI Symbol'
    1F000..1F003, 1F005..1F02B, 1F030..1F093
  'ＭＳ ゴシック'(MS Gothic)
    1F200..1F202, 1F210..1F23A, 1F240..1F248, 1F250..1F251
  hex numbers
    other characters
