Strange subjects

Hi! First, sorry for my english. I have a problem. One of my favorite bookstore sends purchase confirmations. Unfortunately, subjects of these e-mails are strange. Other e-mail clients doesn’t have this issue. For example please see attached pictures. I checked .eml file, this is key line:
Subject: =?iso-8859-2?Q?Z=B3o=BFy=B3e=B6 zam=F3wienie nr 45xxxx na kwot=EA ?= =?iso-8859-2?Q?99,51 z=B3?=

I also encountered the same problem.I received a number of mail subject analytic failure.
Email Header For example:
MIME-Version: 1.0
Content-Type: multipart/mixed;
    boundary="__=_Part_Boundary_001_005947.009183"
Subject: =?gb2312?B?yNXG2qO6MjAxNjA1MT?=
     =?gb2312?B?MzAuMDC?=

Looks like it can not be normal analysis.But other products can be normal resolution.

This problem still exists in this version 7.0.27943.0

Hello everybody,

We’re sorry you experience this. Could we please ask you to export an example of these e-mails as .eml and send it to us at hester@emclient.com with a link to this thread?

Thank you,
