Description Nerijus Baliūnas 2014-06-08 22:17:06 UTC

(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

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).

Comment 5 Nerijus Baliūnas 2014-09-18 11:26:35 UTC

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.

Just tested the latest okular-24.05.0-1.fc40 - the bus is still here.
