When I create the message via kmail2 interface, I fill the fields with Cyrillic symbols in utf-8 encoding.
But when I save this message as draft, I see '?????' symbols instead of cyrillic letters in to-cc-bcc fields.

Reproducible: Always

Steps to Reproduce:
Create new message via kmail2 interface and fill the fields:

to: Вася Vasya Иванов <vasya@example.com>
cc: Петя Petya <petya@example.com>
bcc: Маша 123 <masha@example.com>
subject: Тема subject 123
body: Сообщение 123.

Press File > Save as Draft.
Look at the message in folder Draft.

Actual Results:  
To:	???? Vasya ?????? <vasya@example.com>
CC:	???? Petya <petya@example.com>
BCC:	???? 123 <masha@example.com>
Subject:	Тема subject 123
Body:
Сообщение 123.

Expected Results:  
To:	Вася Vasya Иванов <vasya@example.com>
CC:	Петя Petya <petya@example.com>
BCC:	Маша 123 <masha@example.com>
Subject:	Тема subject 123
Body:
Сообщение 123.
