What ⩣ means
Read it as logical OR; check what the bars distinguish. The 2000 proposal notes that some mathematical symbol names describe shape rather than one fixed function. Use the surrounding notation to understand what these bars signal.
The same 2000 ISO/IEC proposal lists ⩣ among additional mathematical symbols meant to fill gaps in encoded notation. It was coordinated with STIX, a math-font project for scientific publishing.
