Emojis in black and white ( not color and not displayed correctly).

[Héctor Sales Llamas]

Hi, ello everyone,

When I press the combination keys "Meta + ." the emoji selector is launched and these are shown in black and white and many of them are not displayed correctly. I have installed the package: "fonts-noto-color-emoji" and "fonts-noto-*"

I found a solution.. but it seemed dirty to me. I will add this at end of the file ~/.config/fontconfig/fonts.conf

Note: I installed in a virtual machine (VirtualBox) kubuntu 20.04 and these by default are shown in color. My question: I want to install an additional package or some additional steps are required.

Best regards,

Héctor

Hi Héctor!

That's a fontconfig config. I have never dealt with it, but either
another step should be taken from within Plasma or fontconfig itself
:-/

Hello everyone this problem is fixed with plasma version 5.20. At the moment there is a trick:

sudo nano /etc/fonts/conf.avail/66-noto-color-emoji.conf

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <match target="scan">
        <test name="family"><string>Noto Color Emoji</string></test>
        <edit name="charset" mode="assign">
            <minus>
            <name>charset</name>
                <charset><range>
                    <int>0x0</int>
                    <int>0x1F599</int>
                </range></charset>
            </minus>
        </edit>
    </match>
    <match target="pattern">
        <test name="family" compare="contains"><string> </string></test>
        <edit name="family" mode="prepend" binding="weak">
            <string>Noto Color Emoji</string>
        </edit>
    </match>
</fontconfig>

After enable presets:

$ cd /etc/fonts/conf.d
$ sudo ln -s ../conf.avail/66-noto-color-emoji.conf

Note: In the link (above) there is a very similar solution, but this i think is better!
Note[2]: The trick it's from Antonio Rojas Archlinux (Plasma KDE Maintainer).
