U+2913 Downwards Arrow To Bar

U+2913 wurde in Version 3.2 in 2002 zu Unicode hinzugefügt. Er gehört zum Block U+2900 bis U+297F Supplemental Arrows-B in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Math Symbol und wird allgemein verwendet, das heißt, in keiner speziellen Schrift.

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+2913 mit ähnlichen Zeichen bildet, verbietet in sich Zeilenumbrüche.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

Scroll Lock (⤓ or ⇳) is a lock key (typically with an associated status light) on most IBM-compatible computer keyboards. Depending on the operating system, it may be used for different purposes, and applications may assign functions to the key or change their behavior depending on its toggling state. The key is not frequently used, and therefore some reduced or specialized keyboards lack Scroll Lock altogether.
Pressing Ctrl+Scroll Lock performs the same function as pressing Ctrl+Pause/Break. This behavior is a remnant of the original IBM PC keyboards, which did not have a dedicated Pause/Break key. Instead, they assigned the Pause function to Ctrl+Num Lock and the Break function to Ctrl+Scroll Lock.
