(I'd suggest adding mobi or mobipocket backend to bugzilla) Attached epub file is displayed correctly, while mobi lacks some parts of text. For example, page 10-11 has the text in epub: "– Tikrai? Buvai pratęs elgtis su manimi ganėtinai storžieviškai! – Tai, – pareiškė jis, – kas kita. Broliai tam ir yra, kad būtų storžieviai ir retkarčiais mandagiai elgtųsi su seserimis. Apie ką gi mąstei? – Tėtis, – lėtai pradėjo Dorotėja, – neturėtų pageidauti, kad būčiau amžiams gyvendinta Londone, net jei – ir Arnsvort rezidencijoje." while mobi file has: "– Tikrai? Buvai pratęs elort rezidencijoje." Kindle reader displays mobi file correctly, the same as epub example above. Reproducible: Always
Created attachment 87076 [details] epub file (displays correctly)
Created attachment 87077 [details] mobi file (displays incorrectly)
Yep :/ Sadly we don't have much people around with mobipocket expertise so it may take a while for the bug to be fixed (if you know how to code, this is your oportunity!). Thanks for reporting the bug :)
The same happens with FBReader, so I reference here its bug report - https://github.com/geometer/FBReader/issues/255 (if they use the same code for mobipocket support and fix it first).
FBReader fixed it by writing their own mobipocket engine - https://github.com/geometer/FBReader/issues/255#issuecomment-55952380 : It's our own engine, and it is GPL'd as FBReader itself. This new engine is written in C++ instead of the old one written in Java. In fact it is based on our FBReader C++ code, it was improved and fixed last few weeks.
Thanks for the heads up, maybe someone can make our generator use your library or similar if has time.
