Style/RedundantFormat does not currently handle control characters properly, they need to be kept escaped and not replaced with their actual string representations.

NOTE: \s will be replaced with a space regardless, because that's how Ruby handles \s, it does not keep it as an escape character.

[1] pry(main)> "\s"
=> " "
