I'm a newbie on this forum.
I am trying to get cyrillic to display in epub. I used Calibre to create an epub file. The file displays Cyrillic in Calibre without problems.
Now I am trying to use Sigil to embed the fonts. I've added the liberation fonts to the epub file and modified the css. Saved epub.
Now, when I try to open it in Adobe Digital Editions, the ToC on the left displays in Cyrillic, but the text itself is ????????????....
I suspect I need to add or change something else, but what?
