Why is this font working with h1 but not with p?

morty92222 · 04-01-2021, 03:44 AM

So I've been trying to figure out why the font is not working. It shows fine on Calibre but on iPhone or macOS (iBook) it is not working. Only the h1 seems to be working.

The book is 3 lines only. Could someone please take a look and advise. I am going crazy here.

I tried to delete all epubs on my Books app but it didn't help.

Thanks.

Are you really using iBooks or Books? iBooks is one of a number of old versions and Books newer.

At a quick look at the epub, since it is an epub3 file, you need to add the metadata entry: <meta property="ibooks:specified-fonts">true</meta> to the content.opf file in the metadata section. I've done that in your sample epub and attached the modified version to this message. Let me know if if works.

I tried it but it did not work. Also the attached file is having the same problem. As someone mentioned above, I am not using iBooks, I am using Books app that comes with macOS Big Sur and iOS 14.

Everything seems to be working in Sigil. However, viewing them on those 2 apps does not reflect that. I attached a pic from Sigil along with what I see in Books. As you can see, for some reason, the h1 is correct and the font is used. However, for p, this is not the case.

Thank you for trying to help me!

Attach your modified version so the OP can see exactly what it is you did.

He attached it. But it does not work. I can see the modification he did.

Your font declaration appears to contain some redundant entries. Also since this is an epub2 book, you might want to embed a com.apple.ibooks.display-options.xml file. The version that I attached appears to display the correct font in Apple Books on my phone.

Sorry, my screwup. I did the modification for an epub3 for Books/iBooks while doitsu did the correct modification with the com.apple.ibooks.display-options.xml file for an epub2. All I had to do was to look at the top of the screen where Sigil happily said epub2.0.

Thank you. It seems to be working on macOS Books but not on iOS Books. I attached a picture. I also noticed that some of my files which are not working has that file. However, my file is editable on Sigil. Yours is not. I have to open it with VS Code to look into it.

Thank you. However, even after the modification it seems to be working only on macOS Books. iOS Books is still not working and not showing the embedded font.

I was reading documentation for how to make epub for Books and Apple is saying that its apps can handle both epub 2 and 3.

It works with the Apple Books app on my iPhone. You must have a rather old iOS device.

I'm assuming that you're referring to com.apple.ibooks.display-options.xml. That file can't be edited in Sigil, but it never needs to be edited anyway.

That's true, however, Apple seems to prefer epub3 books. BTW, you can convert epub2 books to epub3 books both with Calibre and Sigil.
If you convert your book to an epub3 book, you'll need to add <meta property="ibooks:specified-fonts">true</meta> to the content.opf file. You'll also need to add the ibooks namespace to the <package> tag.
For more information, see the Apple Books Asset Guide.

I have iPhone 11 Pro with iOS 14. I have no clue how you got that to work! You just download the attached file? I did that and as the screenshot shows, it did not work!

It does not even show "Original" in font selection on iOS. Also, in Sigil it does not use the font!

Are you sure you did not install the font on your machine?

No, the screenshot was taken when I added my version of your file to Apple Books.

I have an older model, and my font menu shows an Original option, which was checked.

It does show the font embedded in my version on my Windows 10 machine. What version do you use?
