If you have missing emojis in XFCE as i had terminal following informations are for you. I found this on manjaro related forum but it worked for me in my Endeavour OS as well.

Firstly install noto-fonts-emoji

sudo pacman -Syu
sudo pacman -S noto-fonts-emoji

And edit or create /etc/fonts/local.conf to tell the terminal to use installed fonts. Add following content:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>

 <alias>
   <family>sans-serif</family>
   <prefer>
     <family>Noto Sans</family>
     <family>Noto Color Emoji</family>
     <family>Noto Emoji</family>
     <family>DejaVu Sans</family>
   </prefer> 
 </alias>

 <alias>
   <family>serif</family>
   <prefer>
     <family>Noto Serif</family>
     <family>Noto Color Emoji</family>
     <family>Noto Emoji</family>
     <family>DejaVu Serif</family>
   </prefer>
 </alias>

 <alias>
  <family>monospace</family>
  <prefer>
    <family>Noto Mono</family>
    <family>Noto Color Emoji</family>
    <family>Noto Emoji</family>
   </prefer>
 </alias>

</fontconfig>

This worked for me in my terminal with Jetbrains Mono font. Or you can use any Sans Serif font.
