U+2266 Less-Than Over Equal To
U+2266 was added in Unicode version 1.1 in 1993. It belongs to the block Mathematical Operators 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 mirrored into Greater-Than Over Equal To. If its East Asian Width is “narrow”, U+2266 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 “less-than over equal” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: equal, inequality, less-than, mathematics, over.
The Wikipedia has the following information about this codepoint:
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. The main types of inequality are less than (<) and greater than (>).
