What ୪ means
It writes the value four in Odia numerals.
A distinct Brahmi digit for four is attested by mid-3rd century BCE; Odia numerals developed gradually from that tradition. Inscriptions in Odisha used numerals in practical records and grants. Records of the Bhaumakara rulers preserve older notation; by the 10th century, inscriptions of the Somavamsi rulers show zero in the decimal system.

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.
