What 𫙏 means
In this food name, 𫙏 is read sumi. A Japanese dictionary records 乾𫙏 for karasumi, salted, dried fish roe. The food’s name may echo a Chinese calligraphy ink stick; that theory concerns karasumi, not this character’s origin.
A fisheries history traces salted, dried roe foods to ancient Mediterranean regions. For Nagasaki karasumi, it credits fish seller Takano Yūsuke with a preparation method in 1673–1681, records an offering to the shogun (Japan’s military ruler) in 1712, and counts it among Japan’s three prized delicacies in the Edo period, when shoguns ruled.
Japan’s MJ character collection, designed for names and official records, lists 𫙏 as MJ059091 in Ver.006.02. A font without the glyph may show a blank box.

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
