function Envelope::anyAddressHasUnicodeLocalpart

Returns true if any address' localpart contains at least one non-ASCII character, and false if all addresses have all-ASCII localparts.

This helps to decide whether to the SMTPUTF8 extensions (RFC 6530 and following) for any given message.

The SMTPUTF8 extension is strictly required if any address contains a non-ASCII character in its localpart. If non-ASCII is only used in domains (e.g. horst@freiherr-von-mühlhausen.de) then it is possible to send the message using IDN encoding instead of SMTPUTF8. The most common software will display the message as intended.
