The Yi Jing symbols are hexagrams (called 卦 guà in Chinese), i.e., they consist of six elements.
A very useful symbol font was put together by George Douros: Symbola. This font contains a plethora of symbols from various cultures, among which are not only the Yi Jing hexagrams but also the symbols found in Tài Xuán Jīng. Please make sure to use the font version of Symbola (10.24, January 2018) that is ‘free for any use’. The v. 10.24 Symbola font package can be found on archive.org: Symbola.zip on web.archive.org. Typesetters should use the hinted version of the font.
