U+203F "‿" Undertie Unicode Character

Unicode Version 17.0

U+203F "‿" Undertie is a typographic symbol that resembles a small, inverted breve or curved line placed below the baseline, primarily used in linguistics and phonetics to indicate a close connection or liaison between two adjacent letters or sounds, such as in the transcription of continuous speech or certain African languages. It is distinct from a standard tie bar (U+0361) which appears above characters, and its subtle curvature helps denote a linking pronunciation without breaking the visual flow of text.
