Just tried the new beta version. The font embedding option does not work. In the created epub file, "style.css" does contain the correct font-family name, but the font file is not copied into the epub file.
This is the "style.css" generated by Atlantis:
Code:
body{margin-left:5%;margin-right:5%;margin-top:5%;margin-bottom:5%}
p{text-indent:0.61in;margin-left:0;line-height:24pt;margin-right:0;margin-top:0;margin-bottom:15pt;font-family:華康儷中宋(P);font-size:200%}
.p0{text-indent:0;margin-left:0;line-height:30pt;margin-top:15pt}
.p1{text-indent:0;margin-left:0.33in;line-height:1}
.p3{text-indent:0.61in;margin-left:0;line-height:1}
.t0{font-size:1.27em}
.t1{font-size:1.09em}
.t5{background:yellow}
.t6{font-size:1.09em}
The font-family name is Chinese glyphs.
