U+203F Undertie

U+203F was added in Unicode version 1.1 in 1993. It belongs to the block U+2000 to U+206F General Punctuation in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Connector Punctuation and is commonly used, that is, in no specific script. The character is also known as Greek enotikon.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+203F forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

The tie is a symbol in the shape of an arc similar to a large breve, used in Greek, phonetic alphabets, and Z notation. It can be used between two characters with spacing as punctuation, non-spacing as a diacritic, or (underneath) as a proofreading mark. It can be above or below, and reversed. Its forms are called tie, double breve, enotikon or papyrological hyphen, ligature tie, and undertie.
