Unicode compliant debian emoji font based on NotoColorEmoji

Default emoji font NotoColorEmoji is near-compliant, but does not attempt to meet unicode standard since 2018:

Excerpt from standard:
Unicode standard: Encoding Stability
Applicable Version: Unicode 2.0+
Once a character is encoded, it will not be moved or removed.

Build:

1. Manually remove NotoColorEmoji.ttf from system (Options in font manager gui, or maybe /usr/share/fonts/truetype/noto)

2. Build, copy out file, and re-install.

git clone https://gut.oily.dad/finn/uc-debian-emojifont.git emfont
cd emfont
mkdir fontvol
docker build -t emojis .
docker run -v $PWD/fontvol:/fontvol emojis:latest

Find NotoColorEmoji.ttf and re-install via method of choice.
