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.

The operators mathematics and programming share — set theory, logic, calculus, comparison. Almost every character here has a LaTeX command, which is usually the fastest way to name the one you mean.
