I believe the json file start with 0xff 0xfe, which mark the file as
UTF-16. The problem is that these two character are invalid at the
beginning of a json file.
The problem have the same root for the xml. UTF-16 file but it pretend
it is utf-8 encoded.
These problems might go away on another OS or with python 3.
Another solution might be to open the file with notepad++ and save as
utf-8, without BOM.
