For future reference, ‽ is called an interrobang!

And to show off another fun character, for languages like Spanish that start a question with an inverted question mark, there's also ⸘, the inverted interrobang.

Though I find the name some people call it, gnaborretni (interrobang backwards), much sillier.

It's called an interrobang. Never really took off but still available in unicode.
