打开include/ckeditor/ckeditor.js，搜索i.font_names，找到字体列表。添加所需的中文字体，添加后为：
i.font_names='微软雅黑/微软雅黑,宋体/宋体,黑体/黑体,仿宋/仿宋_GB2312;楷体/楷体_GB2312;隶书/隶书;幼圆/幼圆;Arial/Arial, Helvetica, sans-serif;Comic Sans MS/Comic Sans MS, cursive;Courier New/Courier New, Courier, monospace;Georgia/Georgia, serif;Lucida Sans Unicode/Lucida Sans Unicode, Lucida Grande, sans-serif;Tahoma/Tahoma, Geneva, sans-serif;Times New Roman/Times New Roman, Times, serif;Trebuchet MS/Trebuchet MS, Helvetica, sans-serif;Verdana/Verdana, Geneva, sans-serif';
然后更新缓存就大功告成了
