Error while de-serialising the following package:

'\x85\xa8Coalesce\xc3\xa5Event\xa4user\xa5LTime\xcc\x01\xa4Name\xa4test\xa7Payload\xc4\x03foo'

It should be decoded to the following object:

>>> import msgpack
>>> p = '\x85\xa8Coalesce\xc3\xa5Event\xa4user\xa5LTime\xcc\x01\xa4Name\xa4test\xa7Payload\xc4\x03foo'
>>> msgpack.loads(p)
{'Coalesce': True, 'LTime': 1, 'Payload': 'foo', 'Event': 'user', 'Name': 'test'}

    Fixed in 2.0.0 (#25687, e04c9b5). The Python msgpack wire in this issue unpacks correctly; regression coverage is in test/regression.test.js.

    Repro on master e04c9b55 with the python-msgpack latin-1 wire from this issue:

    Coalesce true
Event user
LTime 1
Name test
Payload Buffer "foo"

    Covered by unpacks a map written by Python msgpack (msgpack-node#10). Closing as fixed in 2.0.0.
