U+21EC Upwards White Arrow On Pedestal with Horizontal Bar

U+21EC was added in Unicode version 3.0 in 1999. It belongs to the block U+2190 to U+21FF Arrows in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as capitals (caps) lock.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+21EC forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Caps Lock ⇪ Caps Lock is a button on a computer keyboard that causes all letters of bicameral scripts to be generated in capital letters. It is a toggle key: each press reverses the previous action. Some keyboards also implement a light to give visual feedback about whether it is on or off. Exactly what Caps Lock does depends on the keyboard hardware, the operating system, the device driver, and the keyboard layout. Usually, the effect is limited to letter keys. Letters of non-bicameral scripts (e.g. Arabic, Hebrew, Hindi) and non-letter characters are generated normally.
