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 subset characters
Unicode names 10 characters ending in “subset”. 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.
