Will 〺 survive being pasted?
- Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites 〺 as
卅. Safe for display, not for storage. - Legacy encodings. 〺 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 punctuation Chinese, Japanese and Korean typography needs — the ideographic full stop and comma, corner brackets, the iteration mark, and the wave dash.
