Vivaldi font showing on calibre file preview, but not on Adobe Reader (Newbie Alert)

[lina.w]

Hello!

Before I begin describing what I'm having troubles on, I just want to let you guys know that I am completely new to calibre. As a matter of fact, I'm a newbie to this whole editing ebook stuff. I've tried to read and understand things that people have said on this forum but end up clueless most of the time. So I hope you guys will be patient with me!

So I have this ebook (in EPUB format) and I've wanted to change the fonts of the headers of the chapters. I wanted to use Vivaldi so I was messing around and say that there is a 'Manage Fonts' button, so I clicked on that. I changed one of the fonts from there to Vivaldi (because it wasn't there before). When I change the chapter headers' font to Vivaldi, the file preview actually shows the Vivaldi font, but when I convert the book to PDF and open it using Adobe Reader, the font doesn't show. I've tried clicking on the 'Embed all fonts' button, but it doesn't embed the one for Vivaldi.

Here's a part of the message:

Embedding font Times New Roman Bold from c:\windows\fonts\timesbd.ttf
Embedding font Times New Roman from c:\windows\fonts\times.ttf
Failed to find font matching: family: Vivaldi; weight: 700; style: normal; stretch: normal
Embedding font Times New Roman Italic from c:\windows\fonts\timesi.ttf

I did some research and pretty much spent the whole night trying to get the font to show on Adobe Reader, but nothing worked. I tried using the @font-face thing, but that didn't do much. I tried putting the @font-face portion on the stylesheet and on the 'Extra CSS' part when you click on 'Convert Books', but nothing worked.

Here's the @font-face thing I used:

@font-face {
font-family: "Vivaldi";
src: local("Vivaldi Italic"),
url(C:\Windows\Fonts\VIVALDII.TTF);
}

I know I must have done something incredibly stupid, but I've no clue what I should be doing. Can someone please explain what I should be doing to get the Vivaldi font to show in Adobe Reader? Thank you so much in advance!

Vivaldi is not allowed for embedding. See attached details of Liberation font and Vivaldi font and compare Font embeddability. Both are free but Liberation allows embedding and Vivaldi not.

Thank you so much!! That explains why no matter what I did, the font never showed.
