Kindle for PC and 'print replica' books - no error but corrupt text

[Hecatron]

Hi, so I recently tried converting a book under calibre I'm using the latest calibre and ddrm versions From what I can gather it's a "print replica" book, in that inside kindle you can't alter the font / size etc. I downgraded the kindle for windows app to 1.34.1 then used the special batch file to get around the kfx issue The type of file shows up as Mobi The front image looks fine, metadata is fine, but the text is all corrupted. Things work fine for other books which are not "print replica" ones

There doesn't seem to be an error which is interesting in the log

One interesting thing I noticed is that the print replica books seem more readable when zoomed right in on the windows kindle app while using the older version of the windows kindle app. With the more recent kindle version, the page jumps about with moving the mouse over sections which I suspect is a bug related to that new crappy kfx standard, which is why I tried to use calibre.

My Environment

Calibre: 5.39.1

Kindle: 1.34.1

DeDRM: 7.2.1

Ok so I just figured this out The solution was to install the KindleUnpack plugin Then run that to extract the book as a pdf

Now it reads fine :)

This is bug in DeDRM. The file is actually a pdf in a mobi wrapper. Use the KindleUnpack plugin to extract the pdf.
