Jackson JSON parser invalid utf-8 start byte
The character at column 33 is –, and the reason this would be the byte 0x96 is that the file is physically encoded as Windows-1252. You need to save the file in UTF-8, windows-1252 is not a valid encoding for json. How to do this depends on what text editor you are using.
See JSON RFC:
Encoding
JSON text SHALL be encoded in Unicode. The default encoding is
UTF-8.
