U+1D373 "𝍳" Ideographic Tally Mark Two Unicode Character

U+1D373 "𝍳" Ideographic Tally Mark Two is a numeric symbol from the ancient Chinese counting system used for tallying and record keeping on bamboo or wooden slips. It represents the number two in a system where marks are accumulated to form values, typically written as a horizontal stroke for the first unit and a vertical or diagonal stroke for the second, often appearing in groups of five. This character is part of the Tai Xuan Jing Symbols block in Unicode, which encodes symbols from the Chinese text "Tai Xuan Jing," a philosophical work that includes tally marks as part of its divinatory and counting methods. Its inclusion ensures digital preservation of a historical writing practice that predates modern Chinese numerals.
