"ctrl+shift+u codepoint enter"

[Pierre-Henry F.]

Hello,

Is there a way to make Emacs accept utf8 characters as other applications do on linux using IBus?
For example, `ctrl+shift+u 1642 enter` should be interpreted as the character `ᙂ` but is does not.
How to make this happen?

Many thanks,
PHF

Not sure about IBus, but you could try

(define-key global-map (kbd "C-S-u") 'insert-char)

(Emacs' default binding for insert-char is C-x 8 RET).

With the neat feature that you don't have to hammer in the hex code,
but you can also start typing "smi" and TAB and you are offered all
the codes whose Unicode name starts with SMI, from "SMILE" through
"SMILING CAT FACE WITH HEART-SHAPED EYES" up to "SMIRKING FACE".

Can IBus do that?

With the neat feature that you don't have to hammer in the hex code, but you can also start typing "smi" and TAB and you are offered all the codes whose Unicode name starts with SMI, from "SMILE" through "SMILING CAT FACE WITH HEART-SHAPED EYES" up to "SMIRKING FACE".

Well, my keycodes are sent from a keyboard configured with QMK. The nice thing is that it works in most applications except Emacs.

The keyboard sends the "ctrl+shift+u 1234 space" sequence of bytes that is interpreted as the U+1234 Unicode Character.

And if you use Helm, C-c h 8 (bound to `helm-ucs`) is like C-x 8 RET but
also shows the characters themselves, not just their unicode names
(although it takes a while the first time it's invoked in a session as
it "collects" the characters...)

AFAIK `C-x 8 RET` also shows the characters themselves (next to their
name).

For plain C-x 8 RET, you need to press TAB (once or twice) before
those show up (whereas I think Helm will show completion candidates
more eagerly).

Right, that's also my understanding, but his comment specifically says
"not just their unicode names", so it seems to be hinting at
something else.

I stand corrected. On my config C-x 8 RET is handled by Helm too and
doesn't show the characters, I had forgotten the vanilla C-x 8 RET does.

Thank you all for your kind messages.

So, here is where I got:

    (define-key global-map (kbd "C-S-u") 'insert-char) ;; Thanks for that!

    $ setxkbmap us

    at: https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_unicode_common.c#L109#L124
    replace: `tap_code(KC_SPC);`
    with: `tap_code(KC_ENTER);`

    Compile & flash the thing;

    It works!


Problem: I need `$ setxkbmap fr`. With `fr` everything breaks again...

Try C-q, which normally runs quoted-insert.

By default, emacs reads octal rather than hex, but I
have the following in my .emacs.el file:

     (setq read-quoted-char-radix 16)

Because emacs doesn't know a priori how many digits
you're going to type, you may have to press a non-digit
key (e.g., space) to terminate the input.
