Open the file in the root directory of UEditor directly, find "Set default fonts and font sizes", and modify the default fonts and font sizes:
.....
//Set the default font and font size//font-family cannot be changed casually, fillchar will have parsing problems under safari
//Comment out the original default font and font size//'body{margin:8px;font-family:sans-serif;font-size:16px;}' +
//Modify it to the default font and font size you need'body{margin:8px;font-family:Microsoft Yahei,Microsoft YaHei;font-size:14px;}' +
....
If the font inside the option does not have what you want, you can do it in the root directory Find "Font settings”, uncomment add your new font or delete unwanted fonts:
....
