Will Ⓢ survive being pasted?

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

Other s characters

Unicode names 4 characters ending in “s”. They differ by direction, weight or decoration rather than by meaning.

Nearby in Enclosed Alphanumerics

Letters and digits inside circles, parentheses and full stops. Widely used for numbered lists in plain text, though NFKC normalisation strips the enclosure and leaves the bare character.
