Laravel 5 how to encode To: field when sending mail Mail::send()?

Question

Character encoding

There is this code:

Mail::send('emails.email', [], function($message) {
   $message->
   subject('Тестовое письмо')->
   from('[email protected]', 'Имя отправителя')->
   to('[email protected]', 'Имя получателя');
});

If the recipient's name is written in Cyrillic in the To: field, then the letter does not arrive.
Do I need to encode this field myself?
If so, how?
All sources are in UTF-8 without BOM.

This helped:

to('[email protected]', '=?utf-8?B?'.base64_encode('Имя получателя').'?=');
