U+21B8 North West Arrow To Long Bar

U+21B8 was added in Unicode version 1.1 in 1993. 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 home.

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+21B8 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “north west arrow long bar” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow, bar, long, north, west.

The Wikipedia has the following information about this codepoint:

The Home key is commonly found on desktop and laptop keyboards. The key has the opposite effect of the End key. In limited-size keyboards where the Home key is missing the same functionality can be reached via the key combination of Fn+←.

Its standard symbol ⇱ from ISO/IEC 9995-7, i.e. U+21F1 ⇱ NORTH WEST ARROW TO CORNER, is used on some full-size keyboards instead of a possibly localized text label.
