What 甋 means
In 瓴甋, it names a brick or paving block.
《爾雅》, an early Chinese dictionary, equates 瓴甋 with 甓. A commentary on a poem in 《詩經》, an anthology of classical Chinese poems, describes 甓 paving a courtyard passage. A Yuan-era poem uses 瓴甋 for a bottle-shaped earthenware vessel, so the surrounding words settle which sense applies.
Classical and specialist; in everyday prose it reads as bookish historical vocabulary.

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.
