Will ， survive being pasted?

Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites ， as ,. 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.

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.
