I guess the cause of the problem is non-English string in font-familiy property. If I select some other font (Chinese font with English font-family name), Atlantis can embed the font into epub.
This is the correct "style.css":
Code:
@font-face{font-family:"Wingdings";font-style:normal;font-weight:normal;src:url(fonts/WINGDING.TTF)}
@font-face{font-family:"iLiHei";font-style:normal;font-weight:normal;src:url(fonts/iLiHei090611.ttf)}
body{margin-left:5%;margin-right:5%;margin-top:5%;margin-bottom:5%}
p{text-indent:0.61in;margin-left:0;line-height:26pt;margin-right:0;margin-top:0;margin-bottom:15pt;font-family:iLiHei;font-size:200%}
.p0{text-indent:0;margin-left:0;line-height:1}
.p2{text-indent:0;margin-left:0;line-height:1;page-break-before:always}
.t0{font-family:Wingdings;font-size:1.27em}
.t1{font-size:1.27em}
.t2{font-family:Wingdings;font-size:1.09em}
.t3{font-size:1.09em}
.t6{font-size:1.09em}
.t7{font-size:1.27em}
