builtins.UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 7: invalid continuation byte

When I input Chinese, the above error appears, English is normal

cmd: curl -XPOST localhost:5000/parse -d u’{“q”:“明天报”, “project”:“chat_nlu”, “model”:“chat_nlu”,“Content-Type”:“utf8”}’

Try to use the UTF8-BOM encoding…

还是不能解决我的问题,我该怎么办?
