What ◤ means
◤ is the black upper left triangle. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Geometric Shapes 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+25E4. In HTML that is ◤, and in CSS \25E4.

1Why does ◤ show as a box on some devices?
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.
