Certain EPUBs cannot be opened correctly in ADE (Windows, Android, iOS)

I found some EPUBs cannot be loaded correctly. This issue happened on all platforms (Windows, Android, iOS. I don't have mac devices, but I guess it would exist on mac as well).

SCENARIO 1: Non-English Characters cannot be displayed correctly.

Not all EPUB files have this problem.

SCENARIO 2: Photos cannot be displayed completely in screen.

Again, not all files have this problem. As I cannot attach a file, I can only show screenshots here.

For this issue, one of the reasons I guess is the picture is much larger than the screen. But why not zoom it to show a full scene?

I have sample files for the two issues. So please let me know how I can send you.
