Implicit encoding sounds like a bad behaviour. Yes indeed, hence my question on python-dev...

Looking at the FileHandler source ( http://svn.python.org/view/python/trunk/Lib/logging/__init__.py?view=markup ) : the utf-8 encoding is a fallback. But *FileHandler family let you specify the encoding you want, so that's OK I think. But SMTPHandler does not have such a thing it sends its email with : msg = "From: %s\r\nTo: %s\r\nSubject: %s\r\nDate: %s\r\n\r\n%s" % ( self.fromaddr, ",".join(self.toaddrs), self.getSubject(record), formatdate(), msg) .... smtp.sendmail(from,to,msg) And there is no encoding in all this. It seems pretty dangerous to me (so my first post) because your application will work without any problem with a FileHandler and the day you'll decide to send email in case of serious problem, it will crash with a UnicodeError. I can't see any workaround, except by subclassing SMTPHandler's emit method to be unicode-aware or at least URF-8 aware.

Implicit encoding sounds like a bad behaviour. UTF-8 is only used as a fallback in an exception handler, you can use any supported encoding using the encoding= keyword argument to a FileHandler. > > I suggest you report an issue onhttp://bugs.python.org Yes, please do that and I will investigate.
