AZW4 to epub issue

golfnt · 08-18-2015, 10:32 AM

I'm new to Calibre and have an issue I could use some help with.
The attached file outlines the problem.
Any help would be appreciated.
Let me know if I should provide more info/detail.
Thanks
Dan

Expecting people to download and risk opening an attachment from a complete stranger is unwise. Just explain your issue in simple plain text, inline, please

AZW4 is a PDF is a wrapper. Conversion to ePub results in all the usual problems one would expect when doing a conversion from PDF.

Use the KindleUnpack plugin to extract the PDF if you just want to use on other devices.

The following is most of the content of the doc attachment -
screen shots didn't copy.
I am new to Calibre and experimenting with moving a AZW4 book "Elements of Algebra" by Euler to MOBI or ePub format to use with the Marvin reader on an iPad.

The conversion from AZW4 to PDF using KindleUnpack worked fine - all formatting and text characters transferred correctly. However, the conversion from PDF to either MOBI or ePub produces issues of 1) change in line spacing and 2) loss of characters.

The line spacing is annoying but not critical but the loss of characters is a show stopper.

I'm at a loss as to how to proceed next. The strange thing is that the html files produced by debug show no loss of formatting or characters when viewed in Firefox but the viewer in Calibre doesn't display the characters. In addition, when loading the original PDF file into the Calibre viewer, it too doesn't display some characters.

Here are screen shots:

@golfnt - Welcome to Mobileread

I can't see any images. You need to read this Attachments and Images

Try to spend a little time reading the FAQ and Guidelines pages - there are links at the bottom of every page. It's also a good idea to have a quick look at the stickies at the top of a sub-forum before starting a new thread - the information you seek may be there.
