Will ⫓ survive being pasted?
- Normalisation. Yes. ⫓ is unchanged by NFKC, so it survives normalising systems intact.
- Legacy encodings. ⫓ is Unicode-only — it has no Latin-1 equivalent, so a system stuck on an 8-bit encoding cannot represent it.
- Size. 3 bytes in UTF-8. Character-limited fields — SMS, bios, some form validators — usually count bytes, not characters.
Other superset characters
Unicode names 7 characters ending in “superset”. They differ by direction, weight or decoration rather than by meaning.

About Unicode’s Math symbol category
Unicode classifies this as a mathematical symbol, which means software that lays out formulas treats it as an operator or relation and gives it spacing accordingly, rather than setting it tight against its neighbours like a letter.
