What 鈓 means
鈓 is a documented written variant of 銋.
The dictionary entry also gives a curved sword edge as a sense. The compound 鍖銋 describes a slow, muffled sound.
The Chinese dictionary trail for 鈓 includes 玉篇 (compiled in 543) and 龍龕手鑑 (completed in 997). In the Han-era rhapsody 洞簫賦 (a long descriptive poem about a flute), 鍖銋 describes the flute's sound.

1Why does 鈓 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.
