For everywhere else, the output from InDesign should be fine. If you're mangling a font for a book to be sold on iTunes, then you'll need to follow the idpf specs (there's a script from pdurrant floating around on the forum that will do it for you). If your licence obliges you to obfuscate the font in order to embed it then you'll need to prepare different versions. Nothing has changed in the ePub 3 standard, which makes me think the IDPF thinks they can win by rigidly sticking to their guns and sticking their heads in the sand. This has resulted in the present mess where there's a large installed base of ADE-compatible readers using one method of font mangling, and another large base consisting of one device (the iPad) which doesn't (or may use the IDPF method since Apple has recently started to allow font embedding). The big joke is the differences between these two methods are trivial: both generate a key from the epub's first UUID, Adobe uses a 16-bit key XORd over the first 1024 bytes and IDPF hashes the UUID to create a 20bit key XORd over the first 1040 bytes.Īt its root, this issue dates back to the silly political squabbles that occurred a few years ago when the ePub standard was being formed. #2: If I can't have them validate, does it matter for getting them accepted for sale on the Nook or iBooks stores?Īny help you can provide is greatly appreciated. #1: Is it possible to have an ePub with embedded fonts validate with the fonts still working? Someone told me that to get the fonts to validate, I have to edit the encryption.xml andĪfter I do this change, the ePub validates! Sounds great, but the fonts do NOT work any longer! They don't work in Digital Editions or on Nooks (where they did back in step one).ġ is a straight export from InDesign with working fonts, but doesn't validate.Ģ is the same file with the URL changed so it validates, but that stops the fonts from working. Export from InDesign CS5.5 with embedded fonts. Let me explain a bit more of a sample workflow:ġ. My question has to do with getting embedded fonts to validate. If you didn't know, InDesign CS5.5 can embed fonts and they work in Adobe Digital Editions and eReaders using Adobe technology such as the Nook.
