U+21C4 was added in Unicode version 1.1 in 1993. It belongs to the block
This character is a Other Symbol and is commonly used, that is, in no specific script.
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+21C4 forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “rightwards arrow over leftwards arrow” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow, leftwards, over, rightwards.
The Wikipedia has the following information about this codepoint:
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.
