Subject: 24.5; Missing preview of entered unicode codepoints (C-q codepoint
 SPC)

[Message part 1 (text/plain, inline)]

Hello dear Emacs maintainers,


This is an upstreamed report, originally posted on the [Spacemacs GitHub
Issue tracker](https://github.com/syl20bnr/spacemacs/issues/7311).

Today I learned from [this video
tutorial](https://youtu.be/3hwUnhdKWiI?t=4m27s), (link to the 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 a non-digit key, to insert the appropriate unicode character.

However, for some reason, these typed codepoints do not show up in the
echo bar at the far bottom, making it very easy to mistype.

This was first tested in Spacemacs, but is reproducible in emacs -Q.

@TheBB on GitHub responded:

> 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)
> ```



Thank you,

~Wiebe-Marten/Qqwy.

The reason is this commit:

      * lisp/subr.el (read-quoted-char): Use read-key.
      (sit-for): Let read-event decode tty input.

      Fixes: debbugs:14782

Only the second part of the change is AFAIU actually related to
bug#14782.  The change in read-quoted-char (and in at least one more
place not even mentioned in the log) is due to some general issue with
read-event that is hinted at in the comment in sit-for added by this
commit.

If I replace the call to read-key in read-quoted-char with an
equivalent call to read-event, the "C-q" echoing is back.

Stefan, do you see a way to make read-key or the functions it calls
echo the input characters?  I didn't see a way to do that, but maybe I
missed something.

Failing that, I'm inclined to go back to using read-event in
read-quoted-char.  After all, we didn't have any bug reports due to
that, and the echo is a valuable feature, IMO.

A somewhat kludgy alternative is something like the patch below, but
I'm not sure it's justified here.  (It doesn't exactly restore
previous behavior, because the initial "C-q-" prompt appears
immediately, rather than after read-key-delay, but it's close.)

Hmm... it would be good to find such a way, indeed, since the issue is
likely to show at other places where we'd want to use read-key.

Indeed, the scenarios where read-key is preferable to read-event in the
context of read-quoted-char are fairly hypothetical.

So, we should probably revert that for now, but adding a comment about
why we don't use read-key.

Agreed.

OK, will do in a couple of days if no one objects.

The commit I pointed to made 2 more changes in read-quoted-char,
related to the way unread-command-events is set.  I understand that
those two changes also need to be reverted when we go back to using
read-event, right?

Thanks.

Done on the release branch.

I reverted those as well.
