1.6.0 : logging doesn't support non ascii char

[Sylvain]

I've reopened this issue : http://code.google.com/p/googleappengine/issues/detail?id=573

If you try :
logging.info("é")
or logging.info(u"é")

the dev_server crashes.

It was working before 1.6.0 (and it works in production).
I use python2.5.
