U+21FF Left Right Open-Headed Arrow
U+21FF was added in Unicode version 3.2 in 2002. It belongs to the block Arrows in the Basic Multilingual Plane.
This character is a Math 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+21FF forms with similar adjacent characters prevents a line break inside it.
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.
