docstring: Constructor for JSONEncoder, with sensible defaults.
  
          If skipkeys is False, then it is a TypeError to attempt
          encoding of keys that are not str, int, long, float or None.  If
          skipkeys is True, such items are simply skipped.
  
          If ensure_ascii is True, the output is guaranteed to be str
          objects with all incoming unicode characters escaped.  If
          ensure_ascii is false, the output will be unicode object.
  
          If check_circular is True, then lists, dicts, and custom encoded
          objects will be checked for circular references during encoding to
          prevent an infinite recursion (which would cause an OverflowError).
          Otherwise, no such check takes place.
  
          If allow_nan is True, then NaN, Infinity, and -Infinity will be
          encoded as such.  This behavior is not JSON specification compliant,
          but is consistent with most JavaScript based encoders and decoders.
          Otherwise, it will be a ValueError to encode such floats.
  
          If sort_keys is True, then the output of dictionaries will be
          sorted by key; this is useful for regression tests to ensure
          that JSON serializations can be compared on a day-to-day basis.
  
          If indent is a non-negative integer, then JSON array
          elements and object members will be pretty-printed with that
          indent level.  An indent level of 0 will only insert newlines.
          None is the most compact representation.
  
          If specified, separators should be a (item_separator, key_separator)
          tuple.  The default is (', ', ': ').  To get the most compact JSON
          representation you should specify (',', ':') to eliminate whitespace.
  
          If specified, default is a function that gets called for objects
          that can't otherwise be serialized.  It should return a JSON encodable
          version of the object or raise a ``TypeError``.
  
          If encoding is not None, then all input strings will be
          transformed into unicode using that encoding prior to JSON-encoding.
          The default is UTF-8.
