Rare Han ideograph

It points to 蹙: “press, approach, or draw tight.”

A Korean Hanja (Chinese-character) dictionary records 𮨝 as equivalent to 𠑯; a Taiwanese variant dictionary lists 𠑯 under 蹙. Japanese kanji references give 𠑯 the reading ソク (soku), “to press or approach.” 蹙 is cù in Mandarin and 축 (chuk) in Korean Hanja. A later supplement to Shuowen Jiezi, an old Chinese character dictionary, glosses 蹙 as “to press”; the Classic of Poetry and Mencius also use it for shrinking territory and drawing the brow together.
