JSON Invalid UTF-8 middle byte

Question

This error happens when the (Jackson, this case) JSON engine tries to parse some JSON that is not encoded in UTF-8. How to tell the engine that it should expect something different from UTF-8, such as UTF-16? ``` HttpHeaders requestHeaders = createSomeHeader(); RestTemplate restTemplate = new RestTemplate(); HttpEntity requestEntity = new HttpEntity

Accepted Answer

JSON data must be encoded as UTF-8, UTF-16 or UTF-32. The JSON decoder can determine the encoding by examining the first four octets of the byte stream:

```
       00 00 00 xx  UTF-32BE
       00 xx 00 xx  UTF-16BE
       xx 00 00 00  UTF-32LE
       xx 00 xx 00  UTF-16LE
       xx xx xx xx  UTF-8
```

It sounds like the server is encoding data in some illegal encoding (ISO-8859-1, windows-1252, etc.)
