U+1D33D Tetragram for Closed Mouth

U+1D33D was added in Unicode version 4.0 in 2003. It belongs to the block U+1D300 to U+1D35F Tai Xuan Jing Symbols in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+1D33D forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

The Taixuanjing is a divination guide composed by the Confucian writer Yang Xiong (53 BCE – 18 CE) in the decade prior to the fall of the Western Han dynasty. The first draft of this work was completed in 2 BCE; during the Jin dynasty, an otherwise unknown person named Fan Wang (范望) salvaged the text and wrote a commentary on it, from which our text survives today.
