What 𰬀 means
It means tying hair, or the topknot that results. In the Yili (“Rites and Ceremonies”), a classical Chinese ritual manual, the related form 紒 appears in instructions for a young man tying his hair before receiving a cap in a ceremony marking adulthood. A Han-era commentator glosses 紒 as “tying the hair”; an older written form is 結, meaning “tie.” The character names the hair arrangement, not the cap.
Questions people ask
1Why does JavaScript count 𰬀 as two?
Two UTF-16 units. ECMAScript 2026, the JavaScript language standard, defines `String.length` as a count of 16-bit units. 𰬀 uses two such units, so the result is `2` even though it is one symbol.
