It seems, the problem will be resolved by itself.
I have two web servers - for work and for debugging. They work with the same IMAP/SMTP server and with the same mail base.
On the work server PHP 5.6.17 is set. On it the problem is urgent.
On a test server PHP 5.6.25. On it the problem was, but unexpectedly (perhaps, after reset) it was gone. Now Subject and body, both HTML and text are correct.
Now I hope that after updating of the work server the problem will be gone also on it. I will make it tonight.
Best regards, Vladimir Gorpenko

This looks fine. Do you have the same problem if you display the message in both text and html modes?
I think so. I switched the "Prefer HTML" checkbox and opened the letter, I tried to answer in a text format. In both cases characters were wrong.
In this case I'm afraid it uses HTML part only. Just use the HTML/Plain switch in mail preview (upper right corner).
