Save Simple Terminal from symbolic font segfault

The scenario: you are on Debian (or derivatives) and are using the Simple Terminal by the upstream suckless source or community repos such as my soft fork of ST.
The problem: when ST tries to draw symbolic Unicode points—emoji—it
throws an error and quits. This can happen quite often when using TUIs
newsboat: you might get updates that include
such symbols in their title string. I have also seen Git repos where
people use emoji in their commit messages…
sudo apt install fonts-symbola
Everything will then work as intended. Just confirmed as much on a machine running Debian Buster/Sid.
Not needed for graphical applications
To get emoji support on GUIs, I rely on another typeface altogether:
sudo apt install fonts-noto-color-emoji
Then I use the appropriate rules in my fontconfig. The following is
just a sample
fonts.conf. For the fully fledged implementation, refer
to my dotfiles:
<fontconfig> <!-- If the requested font is sans-serif --> <!-- Display sans-serif and then emoji fallbacks --> <match target="pattern"> <test qual="any" name="family"> <string>sans-serif</string> </test> <edit name="family" mode="prepend_first"> <string>emoji</string> </edit> </match> <alias> <family>emoji</family> <default><family>Noto Color Emoji</family></default> </alias> </fontconfig>
All of the above granted, I wish I could do without emoji in my terminal…
