Python email module: form header "From" with some unicode name + email

Question

I'm generating email with the help of Python email module.
Here are few lines of code, which demonstrates my question:

msg = email.MIMEMultipart.MIMEMultipart('alternative')

msg['From'] = "somemail@somedomain.com"

msg.as_string()

Out[7]: 'Content-Type: multipart/alternative;\n boundary="===============9006870443159801881=="\nMIME-Version: 1.0\nFrom: somemail@somedomain.com\n\n--===============9006870443159801881==\n\n--===============9006870443159801881==--' 

As you can see, everything is okay here, From field contains email ant it is cool. But what if I want to add some name before email? Especially unicode one:

In [8]: u.get_full_name()
Out[8]: u'\u0414\u0438\u043c\u0430 \u0426\u0443\u043a\u0430\u043d\u043e\u0432'

In [9]: msg = email.MIMEMultipart.MIMEMultipart('alternative')

In [10]: msg['From'] = "%s <%s>" % (u.get_full_name(), "email@at.com")

In [11]: msg.as_string()
Out[11]: 'Content-Type: multipart/alternative;\n boundary="===============5792069034892928634=="\nMIME-Version: 1.0\nFrom: =?utf-8?b?0JTQuNC80LAg0KbRg9C60LDQvdC+0LIgPGVtYWlsQGF0LmNvbT4=?=\n\n--===============5792069034892928634==\n\n--===============5792069034892928634==--'

Here you can see, that all the string (name, email) was encoded in base64 (and it is even quite logical, how MIMEMultipart will know that string contains unicode and non-unicode parts).
So, my question is: how do I have to tell email module to make me pretty "From" header like:
From: =?UTF-8?B?0JLQmtC+0L3RgtCw0LrRgtC1?= <admin@notify.vk.com> ?

Also, I've learned a little RFC2822 (http://www.faqs.org/rfcs/rfc2822.html , p.3.6.2). It tells:

The originator fields indicate the mailbox(es) of the source of the message. The "From:" field specifies the author(s) of the message, that is, the mailbox(es) of the person(s) or system(s) responsible for the writing of the message. The "Sender:" field specifies the mailbox of the agent responsible for the actual transmission of the message. For example, if a secretary were to send a message for another person, the mailbox of the secretary would appear in the "Sender:" field and the mailbox of the actual author would appear in the "From:" field. If the originator of the message can be indicated by a single mailbox and the author and transmitter are identical, the "Sender:" field SHOULD NOT be used. Otherwise, both fields SHOULD appear.

Does it mean that I should combine these two headers? (From and Sender). I'm a bit confused, because I noticed a lot of emails in my gmail (looking through "Show original") where in From field name and email are presented.

Thanks for help.

You need to encode the name part separately using email.header.Header:

from email.MIMEMultipart import MIMEMultipart
from email.header import Header
from email.utils import formataddr

author = formataddr((str(Header(u'Alał', 'utf-8')), "somemail@somedomain.com"))
msg = MIMEMultipart('alternative')
msg['From'] = author
print msg

I hope this will help.
