While on the topic, this isn’t how passwords work in systems.
Passwords are stored as one way hashes. So it’s cryptoed only in one direction, it’s lossy, and can’t be recovered back to the original password.
When you log on, your cleartext PW is hashed in ephemeral memory/storage and then the cleartext password is thrown away.
That hash is compared to the hash in the DB. If the hash matches, then you have access. If it doesn’t, then your PW is incorrect.
That’s still not how it would work.
Ok, assuming that we’re talking about, like you say, a system that gets a breach which is storing PWs in clear text/plain text, instead of encrypting it, which is a big if as those kinds of systems are either amateur/homebrew, or extinct at this point, but I digress. Let’s say it’s there.
The attacker would run a sanitization script out of the SQL table that would shift those problem characters into proxy characters, or correct them if it’s going to cause a problem. One or two passwords lost to correct for thousands isn’t a big deal. The result of trying to put some sort of SQL Injection or CSV formatting bug into your password, hoping it was stored as plaintext, and the attacker wouldn’t be sanitizing the common formatting issues, is just silly.
Plus, it’s not like they’re only exporting it once. They’ve usually copied the DB down locally, so they’ll see the formatting is skewed when parsing the CSV, and correct it on the next export out.
I’m all for the humor here, I was just calling out that nothing about the ideas the OP suggested would work in real life SecOps scenarios.
