What ⠫ means
Its Braille code determines the reading.
Braille is read by touch. In contracted English Braille, ⠫ is the “ed” contraction inside words; French Braille uses it for ë (“e with a diaeresis”). The code, not the dots alone, sets the reading.
How did Braille develop?
Valentin Haüy made an early tactile text in Paris in 1786 by pressing damp paper against raised type. In 1821, French army officer Charles Barbier demonstrated “night writing” at a school for blind students; its raised-dot code let soldiers read in darkness.
Louis Braille adapted Barbier’s approach into six-dot cells a fingertip could read. He refined the system by 1824 and published it in 1829.

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.
