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.

Characters built out of letters but treated as symbols — ℃ ℉ №, the trademark and service marks, and the script and blackletter letters that mathematics uses as distinct variables. Most normalise back to plain letters, which is worth knowing before pasting one into a password field.
