> There's no guarantee char8_t is 8 bits either, it's only guaranteed to be at least 8 bits. Have you read the standard? It says: "The result of sizeof applied to any of the narrow character types is 1." Here, "narrow character types" means char and char8_t. So technically they aren't guaranteed to be 8 bits, but they are guaranteed to be one byte.
