``` * xreader 3.2.2 * Linux Mint 20.3 Una amd64 ``` **Issue** I have ebook written in Czech language and I see that several Czech characters are not displayed correctly in the index/outline. Content of the book is rendered correctly, I see issue only in the Index. I see that when I open the same book in the Brave browser (it has internal PDF reader), I cannot see this bug, so I assume that ebook is generated correctly and the bug is in the `xreader`  **Steps to reproduce** Download [eBook]( https://uploads-ssl.webflow.com/5e5fcd39a7ed2643c8f70a6a/63f8c3ba1061201ad4fc83f0_21-lekci%CC%81_web.pdf), open it in `xreader` and check Index on the left. **Expected behaviour** Index: * 1 přední * 21 lekcí_print_vers1 * 2 zadní  **Other information** I have found other [ebook example](https://uploads-ssl.webflow.com/5e5fcd39a7ed2643c8f70a6a/645ccdf4abc7577199116c53_lightning-11-5-2023.pdf) and in this book I cannot see this issue, Index has correct characters. So it looks like only some ebooks trigger this issue and others are ok...
