Reverse string, byte-wise.
Reverses the bytes in each string in obj. This operates on bytes (Unicode code units), not characters.
This may well produce invalid strings as a result, because reversing a UTF-8 byte sequence does not necessarily produce another valid UTF-8 byte sequence.
You probably do not want to use this method. You probably want to use
Returns a string array the same size as obj.
