¡I love the interrobang! But I feel like we need more than just that. ⸘Would it not be fantastic to know the tone of a sentence from the beginning‽
Also, I believe what OP is looking for is something like this image. Sadly, I can’t find a keyboard with them, or a copy/pastable line where they’ve been typed. 1000010473
Would also be useful mixed with the interrobang. The backwards question mark “⸮” is also often used for rhetorical questions. But it’s sometimes replaced with ❓because it’s easier to type on a phone. ❗Is sometimes used for sarcastic enthusiasm, too, instead of the “official” sarcmark with is apparently copywrited and difficult to parse because it’s all swirly and weird, whereas the big red ❗ or ❓ is way more obviously out of place and meant to be noticed, like sarcasm or a rhetorical question.
