What 鍿 means
It names a very small historical Chinese weight unit.
The early Chinese character dictionary 說文解字 defines the related graph 錙 as six 銖.
Dictionaries cross-reference 鍿 as a variant of 錙; in simplified Chinese, 錙 is written 锱. The set phrase 錙銖 turns two weight names into a figurative way to describe insignificance.
Historical and specialist; alone, it names an old unit rather than the phrase’s figurative meaning.
For “negligible,” the expression is 錙銖; 鍿 alone names a weight unit.

1Why does 鍿 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.
