Will ｡ survive being pasted?
- Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites ｡ as
。. Safe for display, not for storage. - 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 stop characters
Unicode names 24 characters ending in “stop”. They differ by direction, weight or decoration rather than by meaning.
