What ▬ means
As of 2026, no checked source establishes this glyph's exact origin or original purpose. Its wider family comes from print: attention marks directed the eye, and bullets later organized lists. That explains what the solid bar can do, not a single inherited meaning for ▬.
The reading changes with placement. In a list it works as a heavy bullet or list marker; between blocks it works as a short horizontal divider or separator; in a diagram it can be a filled component. A solid black shape also became an end-of-proof convention associated with Paul Halmos around 1950, but that does not make ▬ a universal proof sign.
This is text, not emoji artwork. Your font draws it, so width, thickness, and alignment may shift between fonts while the character stays the same.
Neutral and typographic; it signals layout more than emotion.
Do not send it alone expecting a hidden meaning.

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.
