Codec error

[R-Suresh]

When I run the model on my windows system I get an error saying,

File "C:\Anaconda3\envs\aristo-mini\lib\encodings\cp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 1412: character maps to <undefined>

I'm guessing its something to with the encoding of the Json files .
could someone help in resolve this error, also which encoding do the Json files use ?
