U+223C TILDE OPERATOR: ∼ – Unicode

U+223C was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as varies with (proportional to), difference between, similar to, not, cycle and APL tilde.

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 Reversed Tilde. If its East Asian Width is “narrow”, U+223C 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 glyph can be confused with one other glyph.

The CLDR project calls this character “tilde operator” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: operator, tilde.

The Wikipedia has the following information about this codepoint:

The tilde (, also ) is a grapheme ⟨˜⟩ or ⟨~⟩ with a number of uses. The name of the character came into English from Spanish tilde, which in turn came from the Latin titulus, meaning 'title' or 'superscription'. Its primary use is as a diacritic (accent) in combination with a base letter. Its freestanding form is used in modern texts mainly to indicate approximation.
