⁂ is a typographical character, not an icon that needs to be inserted as an image. Unique-looking, but standardised. This means it’s very easy to copy-paste around! […]
⁂ is called an asterism. In astronomy, it refers to groups of stars in the sky, akin to constellations. We suggest that it’s a very fitting symbol for the fediverse, a galaxy of interconnected spaces which is decentralised and has an astronomically-themed name. It represents several stars coming together, connecting but each their own, without a centre.
Nice idea. I just followed @liaizon’s example and set the iOS/macOS text replacement feature to expand *** into ⁂.
