What ⡦ means
Not by itself. Unicode encodes this cell's dot arrangement so Braille data can be exchanged and rendered, but it does not assign the pattern one universal letter or word. Different Braille codes can give patterns different meanings, and some use patterns for abbreviations, punctuation, numbers, music, or other notation.
Braille's real-world system evolved from earlier raised-dot experiments. The Library of Congress places Louis Braille's first encounter with Barbier's military code in 1821; Braille refined the larger cell into a fingertip-sized six-dot system and published it in 1829. The purpose shifted from a proposed silent code toward practical literacy for blind readers, then expanded into language-specific, mathematical, musical, and computer codes.
So ⡦ is best understood as an addressable cell pattern, not a secret message. A translator needs the surrounding Braille code and neighboring cells before it can produce a reliable reading.

1Why does ⡦ look different in different fonts?
It can. The glyph is drawn by the font, while tactile Braille depends on raised-dot spacing and a device or physical medium. A screen appearance alone does not prove that a tactile cell has been produced.
