UTF-8
Make sure to use UTF-8 as input encoding for all transferred data. Otherwise the chance for misinterpreted characters is given.
Nil Values Vs. Empty Values
Elements with NIL (or NULL) values must be provided with the nil attribute. Generally, elements with NIL values can be omitted in request bodies. In response bodies, such elements are added unless not specifically required.
