Description: The percontation point (punctus percontativus), or rhetorical question mark, also known as an ironicon was invented by Henry Denham in the 1580s and was used at the end of a rhetorical question; however, its use died out in the 17th century. It was the reverse of an ordinary question mark, so that instead of the main opening pointing back into the sentence, it opened away from it.
Description: Henohenomoheji (へのへのもへじ) or Hehenonomoheji (へへののもへじ) is a face drawn by Japanese schoolchildren using hiragana characters. The word breaks down into the seven hiragana characters: he (へ), no (の), he (へ), no (の), mo (も), he (へ), and ji (じ). The first two he (へ) are the eyebrows, the two no (の) are the eyes, the mo (も) is a nose, and the last he (へ) is the mouth. The outline of the face is made by the character ji (じ), its two short strokes (dakuten) forming the ear or cheek. Children use the Henohenomoheji as the faces of Kakashi (かかし) Scarecrows and Teru Teru Bozu (てるてる坊主) Ghost Dolls.
