The same methods apply to strings as well. +(Note that C<.bytes> is not guaranteed to be well-defined when the encoding +is unknown. Similarly, C<.codes> is not well-defined unless you know which +canonicalization is in effect. Hence, both methods allow an optional argument +to specify the meaning exactly if it cannot be known from context.) There is no C<.length> method for either arrays or strings, because C<length> does not specify a unit.
