What 䗹 means
It corresponds to 䗹, a Chinese character for a hairy caterpillar.
The Shuowen Jiezi, an early Chinese dictionary compiled around 100 CE, defines 蛓 as a hairy caterpillar; later Chinese lexicons identify 䗹 with 蛓. Unicode reserves 䗹 for round-trip conversion with CNS 11643-1992, so text from that Taiwanese character set can move into Unicode and back without losing its source distinction. Unicode normalization can map 䗹 to 䗹; this changes the stored code point, not the word’s meaning.

1Why does 䗹 show as a box on some devices?
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.
