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.
Other bracket characters
Unicode names 24 characters ending in “bracket”. They differ by direction, weight or decoration rather than by meaning.
