Did you read my post? Like, every word of it? Being able to type a control sequence is not particularly useful for ephemeral data in a message-passing between programs context. It's absolutely important for persistent, editable data. It seems like more of a feature to me to use these special characters for special contexts and not have escaping typeable characters be load-bearing.

Further, my editor seems to print control characters just fine, though entering them would be a bit of a pain and the behavior is likely configurable.
