Can't convert EPUB to AZW3

[dalagiorgos]

Hi,

Something must have gone wrong in one of my recent upgrades to Calibre, because today I got an error trying to convert an EPUB to AZW3 for my Kindle Paperwhite.

Here's the conversion error:

calibre, version 3.5.0 (win32, embedded-python: True)
Conversion error: Απέτυχε: Convert book 1 of 1 (Salt, Fat, Acid, Heat: Mastering the Elements of Good Cooking)

That EPUB file is incorrectly identifying one of its font files as a text file. You can fix that in the calibre editor. Either edit the OPF file to change the declared type, or simply delete the file FONT00009.ttf

Thank you very, very much! I've edited the contents.opf and changed the media-type to application/x-font-truetype for each font ttf file and it worked like a charm!
