中文最好用unicode表示，比如使用宋体是{font-family:\5b8b\4f53;}，使用微软雅黑是{font-family:\5fae\8f6f\96c5\9ed1;}

结论

各个手机系统有自己的默认字体，且都不支持微软雅黑
如无特殊需求，手机端无需定义中文字体，使用系统默认
英文字体和数字字体可使用 Helvetica ，三种系统都支持

/* 移动端定义字体的代码 */
body{font-family:Helvetica;}

/**html { filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1); }  */
