Sending email. The letter is not sent with Cyrillic

Purpose: you need to send a letter to the mail. The letter has Cyrillic symbols.

The problem: the script works with Latin symbols, but does not work with the Cyrillic alphabet

script:

   Import  smtplibtext =  \   to =  'xxxxxx@gmail.com'  subject =  'xxxx'   # gmail sign in  gmail_sender =  'xxxx@gmail.com'  gmail_passwd =  'xxxxxx'  server = sMTPLIB.smtp ( '' "smtp.gmail.com ',  587 ) server.ehlo () server.starttls () server.login (gmail_sender, gmail_passwd) body =  '\ r \ n'  .join ([ 'to: % S'  class = ""> '' , text])   try :  server.sendmail (gmail_sender, body)   print )   except :   print  (' 'Error Sending Mail ') server.quit ()     
 error: 
  
  Traceback (Most Recent Call Last): : ) File  "" C: /users/babai/pycharmprojects/mail.py "" , line  47 ,  in  & lt; module & gt;  server.sendmail (gmail_sender, [to], body)  file , line  854 ,  'ascii' ) unicodeencodeerror:  'ascii'  codec Can  '' '' t enterode Characters in Position 63-74: Ordinal Not in Range (128)      
 as I understand the problem of encoding. That is, the SMTPLIB module works only with ANSII ??
