Will ⅒ survive being pasted?
- Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites ⅒ as
1⁄10. Safe for display, not for storage. - Legacy encodings. ⅒ 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.

Roman numerals as single characters, and the vulgar fractions beyond the three Latin-1 supplies. A Roman numeral here is one character, not a run of letters, so Ⅷ and VIII sort and search differently.
