I created an EPUB using InDesign CC, and I selected the option of embedding fonts when exporting. Then, I deleted the unnecessary body fonts, and added another one manually (to the package, content.opf and CSS declaration). The EPUB contains now an Adobe font (encrypted) in some paragraphs as well as a Google font (non-encrypted, with free license). The Adobe font should be displayed in the apps supporting encryption (such as Apple Books and ADE), and the Google font, as fallback, in the ones not supporting encryption (e.g. Kindle).
After editing the EPUB, everything is fine in the Kindle Previewer, but I notice that the apps supporting encryption mix characters from both fonts. See attached image.
Here is my CSS:
Code:
@font-face {
font-family:Quicksand;
font-style:normal;
font-weight:normal;
src : url("../font/Quicksand-Regular.ttf");
}
@font-face {
font-family:VAGRundschriftD;
font-style:normal;
font-weight:normal;
src : url("../font/VAGRundschriftD.otf");
}
(...)
p.Numero-capitulo2 {
color:#39a2c4;
font-family:VAGRundschriftD, Quicksand, sans-serif;
font-size:3em;
font-style:normal;
font-variant:normal;
font-weight:normal;
line-height:1.2;
margin-bottom:45px;
margin-left:0;
margin-right:0;
margin-top:0;
orphans:1;
page-break-after:auto;
page-break-before:always;
text-align:right;
text-decoration:none;
text-indent:0;
text-transform:none;
widows:1;
}
Quicksand is the Google font, and VAG Rundschrift D, the Adobe font.
I used the Google font version directly downloaded from the Google Font website (and I did not activate the Adobe Font version in InDesign). I also tried with the OTF version from Font Squirrel, with the same results. The file encryption.xml is kept in the META-INF folder.
Is there a way to make this work as intended without breaking any license agreement? I read the thread about embedding Adobe Fonts in Kindle:
https://www.mobileread.com/forums/sh...d.php?t=342147. I do not want to de-obfuscate the Adobe font, but to use the encrypted and non-encrypted fonts together in an EPUB.
