UEditor 默认字体和字号的修改方法
直接打开UEditor根目录下的ueditor.all.js文件，查找“设置默认字体和字号”，修改默认字体和字号：
.....
//设置默认字体和字号
//font-family不能呢随便改，在safari下fillchar会有解析问题
//注释掉原来的默认字体和字号
//'body{margin:8px;font-family:sans-serif;font-size:16px;}'+
//修改为自己需要的默认字体和字号
'body{margin:8px;font-family:微软雅黑,MicrosoftYaHei;font-size:14px;}'+
....
选项里面的字体如果没有你想要的，你可以在根目录ueditor.config.js里面查找“字体设置”，取消注释添加你新增的字体或删除不需要的字体：
....
//字体设置label留空支持多语言自动切换，若配置，则以配置值为准
,'fontfamily':[
{label:'',name:'yahei',val:'微软雅黑,MicrosoftYaHei'},
{label:'',name:'songti',val:'宋体,SimSun'},
{label:'',name:'kaiti',val:'楷体,楷体_GB2312,SimKai'},
{label:'',name:'heiti',val:'黑体,SimHei'},
{label:'',name:'lishu',val:'隶书,SimLi'},
{label:'',name:'andaleMono',val:'andalemono'},
{label:'',name:'arial',val:'arial,helvetica,sans-serif'},
{label:'',name:'arialBlack',val:'arialblack,avantgarde'},
{label:'',name:'comicSansMs',val:'comicsansms'},
{label:'',name:'impact',val:'impact,chicago'},
{label:'',name:'timesNewRoman',val:'timesnewroman'}
]
....
修改完成后，打开编辑器默认即为自己设置的字体了！
