U+0168 was added to Unicode in version 1.1 (1993). It belongs to the block Latin Extended-A in the Basic Multilingual Plane.

This character is a Uppercase Letter and is mainly used in the Latin script. It is related to its lowercase variant ũ.

The glyph is a Canonical composition of the glyphs U ̃. It has a Neutral East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. In text U+0168 behaves as Alphabetic regarding line breaks. It has type Upper for sentence and ALetter for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

The tilde (/ˈtɪldə/, /ˈtɪldi/; ˜ or ~; also referred to informally as squiggly or squiggle(s)) is a grapheme with several uses. The name of the character comes from Portuguese and Spanish, from the Latin titulus meaning "title" or "superscription", though the term "tilde" has evolved and now has a different meaning in linguistics. Some refer it to a "flourish".

It was originally written over a letter as a scribal abbreviation, as a "mark of suspension", shown as a straight line when used with capitals. Thus the commonly used words Anno Domini were frequently abbreviated to Ao Dñi, an elevated terminal with a suspension mark placed above the "n". Such mark could denote the omission of one letter or several letters. This saved on the expense of the scribe's labour and the cost of vellum and ink. Mediaeval European charters written in Latin are largely made up of such abbreviated words with suspension marks; only uncommon words given in full. It has since acquired a number of other uses as a diacritic mark or a character in its own right. These are encoded in Unicode at U+0303 ◌̃ combining tilde and U+007E ~ tilde (as a spacing character), and there are additional similar characters for different roles. In lexicography, the latter kind of tilde and the swung dash (⁓) are used in dictionaries to indicate the omission of the entry word.
