    99         skipkeys is True, such items are simply skipped.

    102         objects with all incoming unicode characters escaped.  If
    103         ensure_ascii is false, the output will be unicode object.
    104

    106         objects will be checked for circular references during encoding to
    107         prevent an infinite recursion (which would cause an OverflowError).

    110         If allow_nan is True, then NaN, Infinity, and -Infinity will be
    111         encoded as such.  This behavior is not JSON specification compliant,
    112         but is consistent with most JavaScript based encoders and decoders.
    113         Otherwise, it will be a ValueError to encode such floats.
    114 
    115         If sort_keys is True, then the output of dictionaries will be
    116         sorted by key; this is useful for regression tests to ensure
    117         that JSON serializations can be compared on a day-to-day basis.
