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.
Unicode cross-references
The standard points readers of ⬹ at these characters — usually because they look alike, or because one is the correct choice where the other is often used by mistake.
