Description of problem:
Python client is unable to send a message to a queue with multi-byte characters in its name. I tried the example spout and drain scripts from python-qpid package, as well as a very basic example from "Programming in Apache Qpid" guide. The clients say "unrecognised characters line":

[root@lzhaldyb-rhel63x ~]# qpid-config add queue йцукенг
[root@lzhaldyb-rhel63x ~]# echo $?
0
[root@lzhaldyb-rhel63x ~]# qpid-config queues

How reproducible:
100%

Steps to Reproduce:
1. Create a queue with multi-byte characters in the name: 'qpid-config add queue ěščřžýá'
2. Try to send a message to the newly created queue: '/usr/share/doc/python-qpid-0.14/examples/api/spout ěščřžýá'
3.
  
Actual results:
The client is unable to send a message to such an address.

Expected results:
