Getting proper emoji rendering has been so much of a hassle lately that I was thinking of just stamping the actual SVG file of them instead.
Only problem with this is that I’d like to make them actually look like they are part of the text / heading (as in an actual character), although getting the scaling right may be tricky: any ideas?
The SVGs I would like to use are these: noto-emoji/svg at main · googlefonts/noto-emoji · GitHub
The emojis I need to embed in the document are these: 
While this may be possible by putting the image into a box (probably convenient if something rather specific and not so readily available is required, luckily I figured out a way:
mkdir specific-font-typst-needs-to-use
git clone https://github.com/googlefonts/noto-emoji
cp noto-emoji/fonts/Noto-COLRv1.ttf specific-font-typst-needs-to-use
typst compile --ignore-system-fonts --font-path specific-font-typst-needs-to-use test.typ
Hope this helps others!
To add small graphical symbols into ur pdf? Using the (unicode) emojis from fonts is just the straightest way,
You could also take a look at icon/emoji/symbol pkgs in the universe, to use one or to learn how they insert svg into pdf,
This is an XY problem. Get any font file that covers emoji characters and either install system-wide or locally with the --font-path flag or the environment variable. Using SVG replacements sounds like a hell of a more hustle than using a proper font.
