如何摆脱 url 编码，例如“H%E4nde”并改用“H?nde”？我试过
<meta charset="utf-8" />
<meta name="http-equiv" content="Content-type: text/html; charset=UTF-8"/>
<script type="text/javascript" src="js/index.js" charset="utf-8"></script>

That is not UTF-8, that is percent encodingalso known as url encoding.
那不是 UTF-8，即百分比编码，也称为 url 编码。
You can use decodeURIComponent()to convert it back before displaying it
您可以使用decodeURIComponent()在显示之前将其转换回来
$("#quote1 span").html(decodeURIComponent(text1));
$("#quote1 span").html(decodeURIComponent(text1));
