U+1D306 TETRAGRAM FOR CENTRE

U+1D306 was added to Unicode in version 4.0 (2003). It belongs to the block Tai Xuan Jing Symbols in the 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. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is not mirrored. In text U+1D306 behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

The text TΓ i XuΓ‘n JΔ«ng ("Canon of Supreme Mystery", Chinese: ε€ͺηŽ„ηΆ“) was composed by the Confucian writer YΓ‘ng XiΓ³ng (Chinese: ζšι›„/扬雄; pinyin: YΓ‘ng XiΓ³ng; Wade–Giles: Yang Hsiung; 53 BCE-18 CE). The first draft of this work was completed in 2BCE (in the decade before the fall of the Western Han Dynasty). During the Jin dynasty, an otherwise unknown person named Fan Wang θŒƒζœ› salvaged the text and wrote a commentary on it, from which our text survives today.

The Tai Xuan Jing may be consulted as an oracle, much like the I Ching, with grass stalks or six-faced die. A tetragram drawn without moving lines refers to the tetragram description, while a tetragram drawn with moving lines refers to the specific lines.

In the Unicode Standard, the Tai Xuan Jing Symbols block is an extension of the Yì Jīng symbols. Their Chinese aliases most accurately reflect their interpretation; for example, the Chinese alias of code point U+1D300 is "rén", which translates into English as man and yet the English alias is "MONOGRAM FOR EARTH". The monograms are:

  • the unbroken line ( ⚊) for heaven (Chinese: 倩; pinyin: tiān),
  • once broken line ( βš‹) for earth (Chinese: 地; pinyin: dΓ¬),
  • twice broken line ( 𝌀) for man (Chinese: δΊΊ; pinyin: rΓ©n).

Numerically the symbols can counted as ⚊ = 0, βš‹ = 1, 𝌀 = 2, and grouped into sets of four to count from 0 to 80. This is clearly intentional as this passage from chapter 8 of the TΓ i XuΓ‘n JΔ«ng points out the principle of carrying and place value.
