If it's true that modifying my plaintext before putting it through a standard encryption algorithm might affect the security, then it might also be possible that sending, say, an HTML payload is more secure than sending a JSON payload. That would be weird.
Can existing encryption algorithms encrypt any payload or can't they? It would be odd if we're worrying about timing attacks, etc, when we can't even securely encrypt any possible plaintext first.
