I know that my code passes the broken string to the logging module. But maybe
I get the non-ascii byte string from a third party (psycopg2 sometime passes
latin1 byte strings from postgres in error messages).

I like Python very much because "it refused to guess". But in this case, "best effort"
is a better approach.

It worked in 2.5 and will in py3k. I think it is a bug, that it does not in 2.6.
