Bug: can't decode escaped unicode string

[trim21]

unexpected error: json: string unexpected end of JSON input

some other context:

• it works fine if a is an interface{}
• it also works fine if using json.Unmarshal, not NewDecoder()
• this is the minimal case to re-produce this issue, remove any key-value pair from raw json will make go-json works fine.
