Rare form of 賭

The Unicode chart cites the second edition of Hanyu Da Zidian, a major Chinese character dictionary published in 2010, for this exact form and pairs it with 賭.

For 賭, 貝 points to money or valuables and 者 supplies the sound. A later-added entry in Shuowen Jiezi, an early Chinese dictionary, glosses 賭 as 博簺, an old wagering game.

A Three Kingdoms-period essay records players wagering clothing during a game. A later historical account uses 賭 for a poetry contest, showing the word could also describe competing to win.
