This will require committing an emoji font for it to display consistently on all platforms, and an emoji font is pretty large (24 MB for Noto Color Emoji). This would increase repository size a fair bit, while we try to keep it fairly small so it's easy for users to clone (shallow clones aren't suited for contributing).

Of course, we can rely on system fonts as an alternative, but they can't be used on the web platform. We could have a system in place to download then load the emoji font at runtime on the web platform only, but this would add some complexity to the demo's script.

For the demo we can subset emoji font and keep only a few characters used in the project.
