Actually it does work:

$ cat testmail.txt
From: "someone" <someone@example.com>
To: "me" <me@example.com>
Subject: something
Content-Type: text/plain; charset="UTF-8";
Content-Transfer-Encoding: 8bit

foo bar AÄÖÜĎӅ baz

$ file testmail.txt
testmail.txt: news or mail, UTF-8 Unicode text

$ cat foo.py
#!/usr/bin/python3

import sys
from email import message_from_binary_file

sys.stdin = sys.stdin.detach()
msg = message_from_binary_file(sys.stdin)

print("from: ", msg['From'])
print("to: ", msg['To'])
print("subject: ", msg['Subject'])
print("body: ", msg.get_payload())

$ ./foo.py < testmail.txt
from:  "someone" <someone@example.com>
to:  "me" <me@example.com>
subject:  something
body:  foo bar AÄÖÜĎӅ baz

Bye, Andreas
