Will Ⅶ survive being pasted?

  • Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites Ⅶ as VII. Safe for display, not for storage.
  • Legacy encodings. Ⅶ 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.

Other seven characters

Unicode names 9 characters ending in “seven”. They differ by direction, weight or decoration rather than by meaning.

Nearby in Number Forms

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.
