U+2084 Subscript Four

U+2084 was added in Unicode version 1.1 in 1993. It belongs to the block U+2070 para U+209F Superscripts and Subscripts in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint represents the digit 4.

The glyph is a subscript version of the glyph Digit Four. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+2084 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.

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

4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures.
