Mac System Sublime Text 3 Console cannot output Chinese how to handle

PC Configuration MacBook Pro (Retina, 15-inch, Mid 2015)
System version 10.13.2

I installed sublime Text3 on this machine to configure a compiled system Python3 for python3.6.
When I try to use Python3, output,
Print (' China ')
The system gives an error
Unicodeencodeerror: ' ASCII ' codec can ' t encode characters in position 0-1: Ordinal not in range (128)

Add "env" by modifying Python3.sublime-build: {"pythonioencoding": "UTF8"} to fix the problem

After the change, my sublime-build is like this.
{
"cmd": ["/usr/local/bin/python3/", "-U", "$file"],
"File_regex": "^["file \ "(...?) \ ", line ([0-9]*)",
"Selector": "Source.python",
"env": {"pythonioencoding": "UTF8"},
}
