SUMMARY
Okular can not select the last character in a line in Chinese
Here is an example image: https://www.imagebam.com/view/MEBRIJ4
This is an epub book that can be used as an example: https://en.jp1lib.org/book/15645661/134d13

STEPS TO REPRODUCE
1. Open an EPUB file with Chinese characters.
2. Use box selection or text selection to select any line that ends in Chinese.

OBSERVED RESULT
The last Chinese character at the end of the selected line is missing and seems to have become a space.

EXPECTED RESULT
The Chinese characters at the end should be able to be selected.

It's not windows only.

As an example on the given file, go to page 25.

Try to select the last 2 characters of the first line and the first of the second. There's only 2 characters selected, the last of the first line is ignored.
