I f… up my fonts somehow and lost my emojis in VS Code. Then i stumbled over Your post.
Thanks a lot! I just added the aliases to /etc/fonts/local.conf, set the font to monospace in VS Code, Kate and Konsole and now i have my emojis back and even much better now, because systemwide. + 
The font used in the screenshot is noto-fonts-emoji with Noto Mono 9pts as Fixed Width in the font system settings
