(The '⸮' symbol is the rhetorical question mark or percontation point, developed in the 1580s by Henry Denham. Falling out of use in the 17th century, the symbol was designed "so that instead of the main opening pointing back into the sentence, it opened away from it". I can't see myself ever using it again!)
