Will 🄀 survive being pasted?

Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites 🄀 as 0.. Safe for display, not for storage.
Legacy encodings. 🄀 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.
