Hello folks!
I've got a rendering problem with some books with embedded fonts (I'm sending a sample book). It occurs on both Editor and Viewer.
The problem is that all the fonts are displaying italicized. I've already checked and the fonts are ok. Also, they work as suposed in iBooks, ADE, Azardi, Readium and Edge, but fail in Calibre and Sigil.
If I remove the fonts from the book, and keep the reference, then they work correctly on my computer (I have those fonts installed on my system).
What is the problem here? Am I missing something? I doubt it since the books is rendering fine on all thoses apps, with Calibre and Sigil being the exceptions.
In the image below, you can see the embedded version (on the left) and the other one with only referenced fonts (on the right). See that the left one shows the Heading and the first part of the text in a italicized manner. The right one renders correctly.
