If you were unwilling to modify your Sony Reader though (or were using another EPUB capable device) it might be different.
I'm trying to modify a zaobao.com Calibre generated EPUB to work with Adobe Song Std - Light font (unsure if it could be distributed..)
Using following addition to CSS sheet:
@font-face {
font-weight: light;
font-style: normal;
font-family: "AdobeSongStd-Light" ;
src: url(fonts/AdobeSongStd-Light.otf) ;
}
@font-face {
font-family: "AdobeSongStd-Light";
font-weight: bold;
font-style: normal;
src: url(fonts/AdobeSongStd-Light.otf);
}
@font-face {
font-family: "AdobeSongStd-Light";
font-weight: normal;
font-style: italic;
src: url(fonts/AdobeSongStd-Light.otf);
}
@font-face {
font-family: "AdobeSongStd-Light";
font-weight: bold;
font-style: italic;
src: url(fonts/AdobeSongStd-Light.otf);
}
body {
font-family: "AdobeSongStd-Light", serif;
}
It's not working
