Missing preview of entered unicode codepoints (C-q codepoint SPC)

[Qqwy]

Today I learned from this tutorial, starts at time with exact explanation of this feature that you can type C-q, followed by the octal(or, if configured, decimal or hexadecimal) unicode codepoint, followed by non-digit key, to insert the appropriate unicode character.

However, for some reason, these typed codepoints do not show up in the bar at the far bottom (Is it which-key that is in charge of that bar? I am still very new to spacemacs), making it very easy to mistype.

I am not entirely sure if this missing preview (As can be seen in the video, that staple version of emacs does show the typed codepoints) is an issue of Spacemacs or of one of the many packages it works with; please tell me where to take the issue if this is not the correct location for it.

Thank you very much for this amazing editor! 😄

This is reproducible in emacs -Q, therefore it's an Emacs issue, not a Spacemacs issue. Please report upstream.

Is it which-key that is in charge of that bar?

No, that's the echo area.

Looks like quoted-insert users read-quoted-char in the background, which doesn't echo key presses unless it's called with a prompt.

Dirty workaround follows.

(defun read-quoted-char-always-echo (orig-fn &optional prompt)
  (funcall orig-fn (or prompt "Character code: ")))
(defun quoted-insert-always-echo (orig-fn arg)
  (prog2 
      (advice-add 'read-quoted-char :around 'read-quoted-char-always-echo)
      (funcall orig-fn arg)
    (advice-remove 'read-quoted-char 'read-quoted-char-always-echo)))
(advice-add 'quoted-insert :around 'quoted-insert-always-echo)

Looks like @Qqwy reported this upstream as https://debbugs.gnu.org/cgi/bugreport.cgi?bug=24635, which is now fixed on Emacs 25.2 and Emacs 26.1. Can this issue be either closed or labeled as "Emacs 24.1"?

Tried it out with 25.3 and 26.1 and it works properly. This can be closed.

Thank you!
