DiapDealer:
Oh, dear, another problem. So after embedding the font and using your plugin to add the xml file, and adding the following line of code to the content.opf in the metadata section as dictated by Apple--
Code:
<meta property="ibooks:specified-fonts">true</meta>
--Apple have rejected the ePub due to that line of code. This code causes ePubcheck to invalidate the ePub, and my understanding was that I was to ignore this invalidation because that line of code is non-standard, specific to Apple, and just typical Apple bullshit. But Apple have rejected the ePub, citing the same errors as those returned by ePubCheck (see attached ss). Was I wrong in my understanding? Is that line of code ONLY for the .iba format?
I have sent a new file to my colleague with that line of code removed and suggested she try that and see whether or not iBooks recognizes the embedded font without it. In the meantime if you or others are around and can shed some light on this, that would be awesome.
