What 碆 means
A stone arrowhead tied to silk cord for bird hunting.
The Shiji, a Chinese historical chronicle, preserves a written example of the term. The Shuowen Jiezi, a Chinese character dictionary, explains the device.
Archaic and specialist, suited to reading classical Chinese texts or studying characters.
It names a specific hunting implement, not a general arrow or danger sign.

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.
