The question is: What conversion is necessary in order to print the
EmailMessage object to the terminal, such that the quoted-printable
parts are turned (back) into UTF-8?

Do you still have access to `body` ? That would be the original
message text? Otherwise maybe:

The objective is to obtain the message body Unicode text (i.e. a
regular Python string with the original text, unencoded). And to print
that.

So in both cases the subject is fine, but it is unclear to me how to
print the body.  Or rather, I know how to print the body OK, but I don't
know how to print the headers separately - there seems to be nothing
like 'get_headers()'.  I can use 'get('Subject) etc. and reconstruct the
headers, but that seems a little clunky.

Sorry, I am confusing the terminology here.  The 'body' seems to be the
headers plus the 'content'.  So I can print the *content* without the
headers OK, but I can't easily print all the headers separately.  If
just print the body, i.e. headers plus content, the umlauts in the
content are not resolved.

OK, so I can do:

######################################################################
if args.verbose:
    for k in mail.keys():
        print(f"{k}: {mail.get(k)}")
    print('')
    print(mail.get_content())
######################################################################

prints what I want and is not wildly clunky, but I am a little surprised
that I can't get a string representation of the whole email in one go.
