Hi everyone,
I am working on client project (Books epub Creation). When I export book as Epub Fixed Layout and send to my client. He tell me to solve this error " Fonts: Encrypted fonts are used. Not every shop supports encrypted fonts.". 

I have books in 20 languages and each book has different font.
Anyone please help me how to solve this issue. I search a lot and watch videos but unable to solve this issue.
I shall be very thankful to you.
Regards Yasir Ali

One option is to use Sigil to open the epubs, right-mouse click each font in the browser panel and change the Font Obfuscation to "None".

Then save the epub. Fixed.

However, that doesn't mean you are actually allowed to distribute those fonts without encryption, of course.

    Is there a different app that can do this than Sigil? My Mac won't open it, it says it can't be sure there isn't malware in the file

    Sigil is about the only reliable EPUB editor. Calibre is good but for PC only, I think.

     

    EPUBs should never require editing, though. Better to redo the export with the right settings. Also, fonts are encrypted for reasons, so not sure hacking them loose is... appropriate.

     

    That said, I don't think changing the flag in the generated EPUB will magically un-encrypt the fonts. I think it will work only if you have the fonts anyway and want to replace them with un-encrypted versions. But maybe. It would be... fairly stupid for encryption to be controlled by one ASCII file toggle. Reminds me of old video games you could crack with a hex editor and two minutes. 🙂

    The simple answer is to use more widely shared fonts for EPUB, especially those developed for sale or wide distribution. There isn't really any other solution. Or take what books you can to PDF instead of FXL EPUB.
