What ⏧ means
⏧ is the electrical intersection. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Miscellaneous Technical block; this site shelves it under Maths.
Its appearance depends on the font and text styling.
How it is encoded
⏧ is a single code point, U+23E7. In HTML that is ⏧, and in CSS \23E7.
Questions people ask
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.
