What ⨨ means
⨨ is the plus sign with black triangle. Unicode classifies it as a mathematical symbol and files it in the Supplemental Mathematical Operators 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, U2A28. In HTML that is ⨨, and in CSS \2A28.

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.
