Punto interrogativo invertito ⸮

Although in the written English language there is no standard way to denote irony or sarcasm, several forms of punctuation have been proposed. Among the oldest and frequently attested are the percontation point invented by English printer Henry Denham in the 1580s, and the irony mark, furthered by French poet Alcanter de Brahm in the 19th century. Both of these marks were represented visually by a backwards question mark.

These punctuation marks are primarily used to indicate that a sentence should be understood at a second level. A bracketed exclamation point and/or question mark as well as scare quotes are also sometimes used to express irony or sarcasm.

Il simbolo «Punto interrogativo invertito» è incluso nel sotto-blocco «Punteggiatura storica» del blocco «punteggiatura supplementare» ed è stato approvato come parte della versione Unicode 5.1 nel 2008.
