希望可以自动处理\ufeff这个非法字符，一开始没有做处理，fastjson直接报错，跟了半天源码才知道有个非法字符。

数据内容为：
{"status":"1","message":"","page":"1","total":"216","result":[{"carno":"(01#)冀Axxx","terminal":"861001005352980","terminaltype":"垃圾车","sim":"15801710489","frameno":null,"engineno":null,"color":"","orgname":"清运科"}]}

因为返回的内容里面前两个字符带有\ufeff
如：

\ufeff在调试工具下可以看到。
