Using email.policy.SMTP a message's non-ASCII characters are not encoded. The policy.utf8 attribute is set to False as documented.

The attached script illustrates the behaviour. I get the following command line output from it:

Subject: =?utf-8?b?w7zDtsOk?=


False
Subject: üöä


True
Subject: üöä


The default compat32 policy encodes the string, but the SMTP policy does not encode it, but leaves it as UTF-8 despite policy.utf8 == False. I might be misreading the documentation here, but it seems to me like utf8 == False implies that encoding should happen.
