U+2E2E Reversed Question Mark

El Wikipedia tiene la siguiente información acerca de este punto de código:

Irony punctuation is any form of notation proposed or used to denote irony or sarcasm in written text. Written text, in English and other languages, lacks a standard way to mark irony, and several forms of punctuation have been proposed to fill the gap. The oldest is the percontation point in the form of a reversed question mark (⸮), proposed by English printer Henry Denham in the 1580s for marking rhetorical questions, which can be a form of irony. Specific irony marks have also been proposed, such as in the form of an open upward arrow (^△
_|), used by Marcellin Jobard in the 19th century, and in a form resembling a reversed question mark (), proposed by French poet Alcanter de Brahm during the 19th century.

Irony punctuation is primarily used to indicate that a sentence should be understood at a second level. A bracketed exclamation point or question mark as well as scare quotes are also occasionally used to express irony or sarcasm.
