HN intentionally removes “emoji-type” characters (I don’t know what the exact criteria are, it’s definitely more complicated than which plane the character is on) from posts. The only time I’ve seen this cause issues is when trying to discuss Unicode itself; presumably the moderators decided this is an acceptable tradeoff.

Automatically silently stripping characters from posts seems like a bad idea. If we want to forbid characters from posts, wouldn't it be way safer to prevent the post and tell the user to remove them?

There's no obvious criteria. 𓂺

Could you not have picked a different emoji (also why is that a a character?)

It's in Unicode because it's a hieroglyph. Now why is it a hieroglyph I think you would need to ask ancient Egyptians.

Possibly the entire "Miscellaneous Symbols" block?
