…il addresses (#122540) The email generators had been incorrectly flattening non-ASCII email addresses to RFC 2047 encoded-word format, leaving them undeliverable. (RFC 2047 prohibits use of encoded-word in an addr-spec.) This change raises a HeaderWriteError when attempting to flatten an EmailMessage with a non-ASCII addr-spec and a policy with utf8=False. (Exception: If the non-ASCII address originated from parsing a message, it will be flattened as originally parsed, without error.) This also applies to other contexts in which RFC2047 words are not allowed by the RFCs. Non-ASCII email addresses are supported when using a policy with utf8=True (such as email.policy.SMTPUTF8) under RFCs 6531 and 6532. Non-ASCII email address domains (but not localparts) can also be used with non-SMTPUTF8 policies by encoding the domain as an IDNA A-label. (The email package does not perform this encoding, because it cannot know whether the caller wants IDNA 2003, IDNA 2008, or some other variant such as UTS #46.) Co-authored-by: R.

…122477) The email.headerregistry.Address constructor raised an error if addr_spec contained a non-ASCII character. (But it fully supports non-ASCII in the separate username and domain args.) This change removes the error for a non-ASCII addr_spec, as well as the Defect that triggered it. In the unicode era non-ascii is not a defect, though it is an error when an attempt is made to serialize it to ascii. The serialization issue was handled in #122540.
