What 𰣅 means
Yes; 𰣅 is a rare historical graph form linked to 雷. A scholarly transcription of early Chinese bamboo texts preserves this shape.
Bamboo slips are narrow strips of bamboo with writing, joined into manuscripts. Keeping 𰣅 records the graph in that source; for ordinary Chinese writing, 雷 is the usual form for thunder.

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.
