Will ¿ survive being pasted?
- Normalisation. Yes. ¿ is unchanged by NFKC, so it survives normalising systems intact.
- Legacy encodings. ¿ exists in Latin-1 and Windows-1252, so even software that predates Unicode can store it.
- Size. 2 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 question characters
Unicode names 5 characters ending in “question”. They differ by direction, weight or decoration rather than by meaning.
