What ꍒ means
It marks a syllable in Nuosu, a Yi language. In the standard zhex transcription, final x marks secondary-high tone (a high pitch pattern).
Claims that Yi writing reaches China's Western Han dynasty are disputed; a bronze-bell inscription securely dated to 1485 survives. Older forms served bimo (Yi ritual specialists) in religious, magical, medical, and family-lineage texts. A Liangshan standard was devised in 1974, promulgated in 1980, and used in schools and publishing. Unicode, the text standard used by phones and computers, represents Liangshan Nuosu writing, not every Yi tradition.

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.
