What ⤙ means
It marks direction; context supplies the exact role. In a diagram, the left arrow symbol indicates which way to follow. In a formula, use that notation's rules; the arrow alone does not identify a particular relation.
How did arrows become technical notation?
Arrows moved from flow diagrams into formal notation. In 1737, a French engineering treatise used an archer-style arrow to show water flow and a waterwheel's rotation. In 1922, mathematician David Hilbert used an arrow for logical implication. Those examples describe arrows generally, not a fixed meaning for ⤙.

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.
