Will 🆭 survive being pasted?
- Normalisation. Yes. 🆭 is unchanged by NFKC, so it survives normalising systems intact.
- Legacy encodings. 🆭 sits above U+FFFF, so it needs a surrogate pair in UTF-16. Software that counts characters by code unit will report it as two.
- Size. 4 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.
