U+2190 Leftwards Arrow
U+2190 was added in Unicode version 1.1 in 1993. 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. 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. If its East Asian Width is “narrow”, U+2190 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The CLDR project calls this character “left-pointing arrow” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow, left, left-pointing.
The Wikipedia has the following information about this codepoint:
← or <- may refer to:
- an arrow (symbol), character of Unicode
- an arrow key or a backspace on a keyboard
- ←, <<, <-, representing the assignment operator in various programming languages
- a converse implication in logic
- the relative direction of left or back
- "Caused by" (and other meanings), in medical notation
