Wrong formatting of the text using both internal and external readers

Hello, I am facing the issue with both internal and external (Windows Notepad) readers. On my old computer with Windows 7 it works fine. But on my other computer with Windows 10 there is wrong formatting of the text. I can see only strange symbols.

I tried several settings but nothing helped. Can anybody help what to do to see the text correctly?

I use the latest version 6.5.3.

Thank you.

What encoding do your files use?
Do you possibly have different Windows legacy encoding configured on those machines?
Control Panel > Clock and Region > Region > Administrative > Language for non-Unicode programs
If this does not help, please post an example file.
