Byte array to String and back.. issues with -127

Question

In the following:

 scala> (new String(Array[Byte](1, 2, 3, -1, -2, -127))).getBytes
 res12: Array[Byte] = Array(1, 2, 3, -1, -2, 63)

why

Answer 1

StringOps has a method getBytes, I think that is probably what one actually wants for converting String to Array[Byte]
