What ⟈ means
Read its role from the notation around it. Mathematical symbols can serve different roles in different fields; this character’s shape alone does not tell you which one the writer intends. Check the convention used by the formula or subject area.
Why is ⟈ paired with ⟉?
Unicode pairs them as mirror glyphs. In writing that runs right to left, a renderer can display ⟉ as the mirror glyph for ⟈ while the underlying text still contains ⟈.

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.
