Wavy Low Line

It marks a work title, not a pause or feeling.

The modern Chinese title-mark convention took shape in a 1919 proposal for punctuation and was formally adopted in 1920. That reform gave printed prose visible marks for pauses, names, and titles. This is the convention's history; this exact character preserves a legacy typographic form.

For Chinese titles, Taiwan's convention uses the wavy low line under book, chapter, song, film, newspaper, and magazine names in horizontal writing, and to their left in vertical writing. The straight name mark 專名號 marks personal, place, or dynasty names. As of 2026, mainland Chinese standard examples reserve the wavy form for ancient works or certain literary and historical titles; 《》 and 〈〉 mark ordinary modern titles.

What if someone sends ﹏ alone?

It is incomplete title typography, not a reliable mood signal.

The mark needs a title and a layout to do its job. A repeated string such as ﹏﹏ represents the wavy title-mark convention in plain text, but this spacing character does not attach itself beneath preceding words.

Unicode groups it with legacy CJK compatibility forms: characters preserved for older text conventions. For an underline that tracks a title, use an editor's underline style; a line made from separate characters can drift away from the words.
