Will ⓿ survive being pasted?
- Normalisation. Yes. ⓿ is unchanged by NFKC, so it survives normalising systems intact.
- Legacy encodings. ⓿ 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 ⓿ at these characters — usually because they look alike, or because one is the correct choice where the other is often used by mistake.
Other zero characters
Unicode names 5 characters ending in “zero”. They differ by direction, weight or decoration rather than by meaning.
Nearby in Enclosed Alphanumerics
Letters and digits inside circles, parentheses and full stops. Widely used for numbered lists in plain text, though NFKC normalisation strips the enclosure and leaves the bare character.
