Properly encode incoming json message

What steps will reproduce the problem?
1.Any robot message with unicode (non-ascii) characters will cause an 
exception in the appengine log. Here is an example:
08-12 11:01PM 49.150
Traceback (most recent call last):
E 08-12 11:01PM 49.150
  File "/base/python_lib/versions/1/google/appengine/api/app_logging.py", 
line 71, in emit
E 08-12 11:01PM 49.150
    self.stream.write(message.encode("UTF-8"))
E 08-12 11:01PM 49.151
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 371: 
ordinal not in range(128)

What is the expected output? What do you see instead?
No exception should be thrown.

What version of the product are you using? On what operating system? r11 on 
linux (2.6.27-grsec #2 SMP CentOS 4.7)
