As I use +my notifications for messages I get from my work chat, and I dislike seeing the +squares, I set out to find the solution. I've had to string together a couple +sources of information to get to the correct setup, and this blog post intends +to show just the useful bits. So here goes! + +You'll need an emoji font (in my case `fonts-noto-color-emoji`), add two +configuration files for fontconfig, rebuild the fontconfig cache, and most +likely log out and back into KDE. Installing the emoji font is probably the easy +bit and won't need any additional explanation I hope. So let's get started on +the first configuration file, which will enable the Noto emoji font to be used, +and also force it to be used in favour of other emoji fonts if any application +was using that specifically. I have it saved as +`/etc/fonts/conf.d/75-noto-color-emoji.conf`. + +```xml +<?xml version="1.0" encoding="UTF-8"?> +<!DOCTYPE fontconfig SYSTEM "fonts.dtd"> +<fontconfig> + <!-- Add generic family. --> + <match target="pattern"> + <test qual="any" name="family"><string>emoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + + <!-- This adds Noto Color Emoji as a final fallback font for the default font families. --> + <match target="pattern"> + <test name="family"><string>sans</string></test> + <edit name="family" mode="append"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test name="family"><string>serif</string></test> + <edit name="family" mode="append"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test name="family"><string>sans-serif</string></test> + <edit name="family" mode="append"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test name="family"><string>monospace</string></test> + <edit name="family" mode="append"><string>Noto Color Emoji</string></edit> + </match> + + <!-- Block Symbola from the list of fallback fonts. --> + <selectfont> + <rejectfont> + <pattern> + <patelt name="family"> + <string>Symbola</string> + </patelt> + </pattern> + </rejectfont> + </selectfont> + + <!-- Use Noto Color Emoji when other popular fonts are being specifically requested. --> + <match target="pattern"> + <test qual="any" name="family"><string>Apple Color Emoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Segoe UI Emoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Segoe UI Symbol</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Android Emoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Twitter Color Emoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Twemoji</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Twemoji Mozilla</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>TwemojiMozilla</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>EmojiTwo</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Emoji Two</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>EmojiSymbols</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> + <match target="pattern"> + <test qual="any" name="family"><string>Symbola</string></test> + <edit name="family" mode="assign" binding="same"><string>Noto Color Emoji</string></edit> + </match> +</fontconfig> +``` + +The second configuration file, saved as `/etc/fonts/conf.d/local.conf`, simply +adds the Noto emoji font as a fallback. This enables the use of it when an emoji +is going to be rendered. + +```xml +<?xml version='1.0'?> +<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'> +<fontconfig> + <match target="pattern"> + <edit name="family" mode="append"> + <string>Noto Color Emoji</string> + </edit> + </match> +</fontconfig> +``` + +And after this, a relog of your (graphical) session should be all that is needed +in order to make it work. You can easily test it with `notify-send`, or trying +to render some emoji in `konsole`. |
