Null characters (\u0000) in strings?

This issue originally came up when I first reported it on the orhanobut/wasp library, and that issue contains specific examples and screenshots:

https://github.com/orhanobut/wasp/issues/145

While debugging Wasp to solve this, it turns out its gson.fromJson that is creating these strings. Basically when a bit of json like this:

`{"service_code:"WDI"}`

is deserialized into my object, the value that is put into the string is:

`WDI\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000`

Making comparisons such as this, not true:

`object.service_code == "WDI" // => false`

Is this a serialization issue with gson? Is it a memory thing of some sort? (I also saw an empty string get serialized with what looks to be other data.) Or is there some sort of builder setting I am not invoking to do this properly? The code that does the initialization of gson, and the fromJson is pretty drop dead simple:

`new Gson()`
`return gson.fromJson(content, type);`
