We propose the symbol ⁂ to represent the fediverse.
…
⁂ 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.

@ is the symbol for e-mail. # is the symbol for hashtags. ☮ is the symbol for peace. ♻ is the symbol for recycling. ⁂ can be the symbol for the fediverse. ⁂ is standardised as Unicode U+2042, making it ready to copy and insert anywhere.

Looking at how current emojis tend to be hard to distinguish without increasing the font size (I see ~13 px on this page), I’d say the fediverse icon fits the criterion well enough.
Also,
I can see the icon in here well enough
Most Egyptian hieroglyphics are in unicode. However, there are many other reasons for it not to be included.
