bug#15660: 24.3.50; (NS) Non-BMP character 🔔 not shown

[Carsten Bormann]

(insert-char 128276 1 t)

The inserted character is shown only as a background-color box, although
the system has fonts for that character (Apple Color Emoji, on this machine Symbola too).

(what-cursor-position t) says:

             position: 192 of 192 (99%), column: 0
            character: 🔔 (displayed as 🔔) (codepoint 128276, #o372424, #x1f514)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1F514

               syntax: w 	which means: word

bug#15660: 24.3.50; (NS) Non-BMP character 🔔 not shown

[Jan Djärv]

Hello.

This is a general problem with Emacs fontsets, they don't handle Emoji well.
Maybe we shouid have OSX-specific fontsets.

You can try to append Apple Color Emoji as a fallback, by putting this in your .emacs:

(set-fontset-font t nil (font-spec :family "Apple Color Emoji") nil 'append)

Hi, I can see this bell character fine using Symbola on Emacs 25+. I
think it's probably been fixed at some point in the past.

For more information on color emojis on macos see:

    https://lists.gnu.org/archive/html/emacs-devel/2016-06/msg00630.html

I'm going to close this bug report, but if you're still not seeing
emojis using Symbola, please reply and let us know.

bug#15660: closed (Re: bug#15660: 24.3.50; (NS) Non-BMP character 🔔 not shown)

[Carsten Bormann]

Indeed, using 26.0.50, I no longer see the problem either.
So I agree with you having closed the old ticket.

Grüße, Carsten
