如何使用Python3读取包含不同编解码器的数据块的json文件？

Question

我有一个json文件，我必须把它放到MongoDB中。有不同编码的数据段。就像

{
    "Type":"File",
    "Start_Time":"2017-08-07T22:15:16.147Z",
    "Finish_Time":"2017-08-07T22:15:16.147Z",
    "Format":"UTF-16LE",
    "Message":"*' ¾Ò ,'H EÌ1Ò (F\/Ò ©Ì -A'8* ©1H ,( *ÌF ('1 ~‘¾*'¾Ò *H'DDG ~'© A14*   ",
    "Name_DB":"Main"}

以及

{
    "Type":"File",
    "Start_Time":"2017-08-07T22:16:51.462Z",
    "Finish_Time":"2017-08-07T22:16:51.462Z",
    "Format":"ASCII",
    "Message":"SMS_CC_NR-InternType ISDN_NP +923330051108  From: UnkNumb Alphanumeric NR:EVC@ TID: 1123103757111462, Dear Retailer, U have successfully recharged 49 Rupee to 03325047863.Your current balance is 11257.00 Rupee.",
    "Name_DB":"Main"
        }

当我试图读取文件时，它抛出了一个编解码器错误。如您所见，这两个块有不同的格式-utf-16LE和ASCII。你知道吗

如何读取此文件？你知道吗
