1. In typography, an asterism, from the Greek astēr (‘star’), is a rarely used and nearly obsolete symbol consisting of three asterisks placed in a triangle (⁂). It is used to “indicate minor breaks in text”, call attention to a passage, or to separate sub-chapters in a book. It is Unicode character U+2042 ⁂ asterism (HTML: ⁂). In Windows it is possible to use the key combination ALT+8258 to produce the character, but it has very limited support in the default fonts (Arial Unicode MS / Lucida Sans Unicode / MS Mincho).
