Special character in user name lead to weird Email Sender in the mail

[wantdrink]

Hi there,

I tried to show the sender name as a friendly name with code:

user = {"[email protected]": "Admin MyService™"}
yagmail.SMTP(host="smtp.myservice.com",
                           port=25,
                           smtp_starttls=False,
                           smtp_ssl=False,
                           smtp_skip_login=True,
                           user=user,
                           soft_email_validation=True)
service.send(to=to, subject=subject, contents=body, cc=cc, bcc=bcc, preview_only=False)

It's a internal smtp service without username/password needed. I expect to receive the mail and the sender displays as 'Admin MyService™' , but in fact it shows '("Admin MyService™" [email protected] via myservice.com)...'

After removing the ™ the received mail's sender will display as: "Admin MyService".

So it looks like the character ™ leads to the issue. Any suggestion for it?
Thanks.
