This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is a wide version of the glyph Tilde. Accordingly, its width in East Asian Text is fullwidth. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. U+FF5E offers a line break opportunity at its position, except in some numeric contexts. The glyph can be confused with one other glyph.
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.
