Tell me, when reading mail using the standard imaplib with the exception of libraries such email, there are ways different from:
rv, data = imap.fetch(num, '(RFC822.TEXT)')
print("MESSAGE TEXT: ", base64.b64decode(data).decode('UTF-8'))
in order to get the text in Russian from the body of the letter? I mean no import base64, and flag some in imaplib, etc.
