前提：
[color=]平台为Ubuntu;平台为Ubuntu;平台为Ubuntu
因安卓平台字体没法配置，能力有限，没有修改过，WIN平台页没尝试过，正常应该也支持
步骤：
1、Ubuntu安装你需要的字体
参考https://blog.csdn.net/qq_37955704/article/details/117901454
此处略过，网上很多资料
2、安装油猴插件，或者暴力猴，然后安装epubjsgood脚本，脚本地址：
https://greasyfork.org/zh-CN/scripts/416793-epubjsgood
3、具体修改位置说明：

3.1 其中主要新增了一个设置字体的方法setFonttype方法
[Asm] 纯文本查看 复制代码 function setFonttype(fonttype){
var fontname=fonttype+" !important;";
//var fontname="\"font-family\":"+fonttype+" !important;";
//alert(fontname);
// reader.rendition.themes.default({ div: { "text-wrap": "break--word !important;"}});
reader.rendition.themes.default({ "body": { "font-family": fontname}});
reader.rendition.themes.default({ "body": { "word-wrap": "break-word !important;"}});
reader.rendition.themes.default({ "body": { "white-space": "pre-line;"}});
//reader.rendition.themes.default({ "body": {fontname}});
reader.rendition.themes.default({ "p": { "font-family": fontname}});
reader.rendition.themes.default({ "p": { "word-wrap": "break-word !important;"}});
reader.rendition.themes.default({ "pre": { "white-space": "pre-line !important;"}});
reader.rendition.themes.default({ "p": { "white-space": "pre-line;"}});
reader.rendition.themes.default({ "pre": { "word-wrap": "break-word;"}});
//reader.rendition.themes.default({ "p": {fontname}});
reader.rendition.themes.default({ "pre": { "font-family": fontname}});
//reader.rendition.themes.default({ "h2": { "font-family": fontname}});
reader.rendition.themes.default({ "code": { "font-family": fontname}});
}
主要是用reader.rendition.themes.default以及js的!important;强制改变iframe中的字体已经换行样式
部分元素可以打开
3.2 函数调用时机
在页面ready的时候给相关元素添加click事件，其中相关元素在上面样式中定义，一般页面右上角齿轮可以点开，
[JavaScript] 纯文本查看 复制代码 $('span.smaller').click(function() { changeFontSize(-0.1); });
$('span.larger').click(function() { changeFontSize(0.1); });
$('span.black').click(function() { changeBackgroundColor("#F6F4EC"); });
$('span.white').click(function() { changeBackgroundColor("#E1E6D7"); });
$('span.showline').click(function() { changelinestate(""); });
$('span.hideline').click(function() { changelinestate("hidden"); });
//字体绑定事件
$('span.KaiTi').click(function() { setFonttype("KaiTi"); });
$('span.SimHei').click(function() { setFonttype("SimHei"); });
$('span.SimSun').click(function() { setFonttype("SimSun"); });
$('span.STKaiti').click(function() { setFonttype("STKaiti"); });
$('span.STLiti').click(function() { setFonttype("STLiti"); });
$('span.YouYuan').click(function() { setFonttype("YouYuan"); });
$('span.FZJunHeiS').click(function() { setFonttype("FZJunHeiS"); });
$('span.FZFengYaSongS-GB').click(function() { setFonttype("FZFengYaSongS\-GB"); });
$('span.zktqkt').click(function() { setFonttype("zktqkt"); });
$('span.FZZJ-SYTJW').click(function() { setFonttype("FZZJ\-SYTJW"); });
$('span.LXGW').click(function() { setFonttype("\'LXGW Neo ZhiSong Demo 2751\'"); });
$('span.FZFS').click(function() { setFonttype("FZFangSong\-Z02"); });
$('span.HYFSF').click(function() { setFonttype("HYFangSongF"); });
$('span.HYCFS').click(function() { setFonttype("HYCuFangSongJ"); });
$('span.HYFSJ').click(function() { setFonttype("HYFangSongJ"); });
$('span.CloudYuanCuGBK').click(function() { setFonttype("CloudYuanCuGBK"); });
$('span.AaBoruokaishuBold').click(function() { setFonttype("AaBoruokaishuBold"); });
font-family可以在terminal中用fc-list|grep
[color=][安装的字体名称]
可以看到，配置上即可
3.3 页面元素展示添加
[JavaScript] 纯文本查看 复制代码 var divshow = $(".md-content");
//divshow.text("");// 清空数据
divshow.append('字体大小：缩小放大
');
divshow.append('字体：楷体黑体宋体华文楷体华文隶书-->汉仪仿宋简汉仪仿宋简粗汉仪仿宋繁体方正仿宋幼圆方正俊黑楷书粗体幼圆粗方正字迹瘦银体霞鹜新致宋
');
divshow.append('背景：淡黄橄榄 分隔：显示隐藏
');
//divshow.append('背景淡黄橄榄
');
var panelshow = $("#panels");
//divshow.text("");// 清空数据
panelshow.append('loc');
通过上述3个步骤，重启web就可以在齿轮中设置字体，以及code的换行（不用可以注释了），经测试，大部分文件是可以做到更换字体的，但是少部分可能是样式写在p标签内，无法失效更换字体
具体有感兴趣的小伙伴如果配置过程有问题，可以楼下留言，我如果能解决，很乐意帮助
