logic gate buffer with inverted input

Logic gate buffer with inverted input

𜰚 is a one-input logic gate that flips the signal: 0 becomes 1, and 1 becomes 0. A Unicode proposal traces it to the European alternate character table for Sharp MZ computers and groups it with schematic symbols made to join box-drawing lines.

What 𜰚 means

A buffer is a gate that normally passes its input through unchanged. A small circle on an input is an inversion bubble: it marks the signal to be flipped before the gate. That makes this symbol act as a NOT gate, also called an inverter.

It comes from text-drawn schematics

A 2021 Unicode proposal to preserve older computer characters maps this glyph to the E2 entry in the European alternate character table for Sharp MZ home computers. It groups this gate with schematic symbols designed to join light box-drawing lines, so text cells could form circuit diagrams.

Why 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.
