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+1D34F 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 β 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 (θζ) salvaged the text and wrote a commentary on it, from which our text survives today.
