There really isn’t a difference between a character and an emoji beyond an emoji being a stylized rendering of a character, or a character whose use is intended as a pictograph.

They’re all just Unicode code points, although I suppose there’s some distinction between the characters with more context specific meaning or the ones that are more apt to modification a la 🧑‍⚕️👩🏿‍⚕️. But you’ve also got 💲 and $, where “bold dollar sign” is often represented as green, but “dollar sign” tends to be represented in contextual style. Is ☣ a character or an emoji? What about the thousands of “other symbols” as defined by the Unicode spec which may or may not have special character renderings depending on your platform and font?

And yeah, I didn’t know that character existed, so now it’s doubly confusing why anyone is asking for anything. The symbol has meaning, and it’s in the big book of meaningful symbols. Not sure what more they want.
