What ⭑ means
⭑ is the black small star. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Miscellaneous Symbols and Arrows block; this site shelves it under Stars & signs.
Its appearance depends on the font and text styling.
How it is encoded
⭑ is a single code point, U+2B51. In HTML that is ⭑, and in CSS \2B51.

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.
