LocaleCompare encountered inconsistent results with the browser

[hvppy]

var json={
王五:3,赵六:4,张三:1,李四:2,
}

return Object.keys(json).sort(function(a,b){
return a.localeCompare(b);
});
//Browser Results ['李四', '王五', '张三', '赵六']
//jint Results ['张三', '李四', '王五', '赵六']

return Object.keys(json).sort();
//Browser Results ['张三', '李四', '王五', '赵六']
//jint Results ['张三', '李四', '王五', '赵六']

There is inconsistency in the comparison method of localeCompare, and I don't know how to solve it
