U+21A7 Downwards Arrow From Bar

U+21A7 wurde in Version 1.1 in 1993 zu Unicode hinzugefügt. Er gehört zum Block U+2190 bis U+21FF Arrows in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Other Symbol und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Das Schriftzeichen ist auch bekannt als depth symbol.

Das Zeichen ist keine Zusammensetzung. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text handelt es als Other Neutral. Bei einem Richtungswechsel wird es nicht gespiegelt. Das Wort, das U+21A7 mit ähnlichen Zeichen bildet, verbietet in sich Zeilenumbrüche.

Das CLDR-Projekt bezeichnet dieses Zeichen mit „Pfeil nach unten von Strich weglaufend“ für die Verwendung in Screenreader-Software.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle, chevron, or concave kite, usually affixed to a line segment or rectangle, and in more complex forms a representation of an actual arrow (e.g. ➵ U+27B5). The direction indicated by an arrow is the one along the length of the line or rectangle toward the single pointed end.
