I have added args_preview field, I think it should solve most issues about no-ascii.

> We should keep it as str. There is a logic about using ensure_ascii=True, so it makes sure it always returns a string, instead of a unicode object. To the human eye the raw string might look strange, but its represntation in reports and packages will be the correct one.

ensure_ascii=False seem to return a string too.

  >>> json.dumps(a)
  '{"a": "\\u4f60\\u597d"}'
  >>> json.dumps(a, ensure_ascii=False)
  '{"a": "你好"}'
  >>> type(json.dumps(a, ensure_ascii=False))
  <class 'str'>

I think it maybe not hard, for:

we use ensure_ascii=False when we create args field of FederationQueue
object.

but, when we send federation queue object to Thalamus, we will do the
following two steps in send_record, so we alway send unicode escaped
strings to thalamus.

1. json.loads(record.args)
2. json.dumps(vals)

-----------------------------------------------------
 def send_record(cls, record):
        ...
        if (record.method == 'PATCH'):
            if (record.federation_locator):
                # [{resource, fields[{name, value}]
                for arg in json.loads(record.args):
                           -------------------------------
                    ...
                    send_data = requests.request(
                        'PATCH', url,
                        data=json.dumps(vals),
                        -----------------------------------
                        auth=(user, password), verify=verify_ssl)

                        ...

------------------------------------------------------

json.loads work well when ensure_ascii=False:
