TIL about [^], never seen that before. Apparently, it works like a dot but it also matches newlines.

I believe this is the regular syntax for a set of characters (between "[" and "]"), but the caret symbol ("^") is negation when used inside the set. Therefore, it is simply the negation of an empty set of characters.

Oh, me too. I’ve previously used [\s\S] for that.
