The motivating use cases I've seen for this method are to compute the length of encoded data that contains strings, where the strings would be encoded with `getBytes`. The CSR gives the example of encoding multiple large strings into a single array. Specifying the output in terms of `getBytes(cs).length` is necessary for that use-case, and requires the handling of replacement characters and unpaired surrogates to be the same between the two methods. Do you see alternatives that should be considered? ------------- PR Comment: https://git.openjdk.org/jdk/pull/28454#issuecomment-3767013988
