U+21CD Leftwards Double Arrow with Stroke

U+21CD was added in Unicode version 1.1 in 1993. It belongs to the block U+2190 para U+21FF Arrows in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Otro símbolo and is commonly used, that is, in no specific script.

The glyph is a canonical composition of the glyphs Glifo para U+21D0 Leftwards Double Arrow, Glifo para U+0338 Combining Long Solidus Overlay. 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+21CD forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “flecha doble hacia la izquierda tachada” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: doble, flecha, izquierda, tachada.

El Wikipedia tiene la siguiente información acerca de este punto de código:

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.
