eM client inbox email title encode issue: show unreadable characters for chinese words

My em client show inbox messages with unreadable characters for chinese words.

Here is the screen shot:

And my full release number of em client is 8.0.3283(42db578).

Is there anything I set up wrongly?

Thanks a lot!

One thing you can try is to upgrade to the latest version available in the Release History and see if there is any difference.

I tried the latest release, 8.1.857. Nothing changes. The message title is still unreadable.

Any other suggestions?

Thanks a lot!

It looks like a character decoding problem. Maybe change fonts in Settings-Appearance-Fonts could help?
