Question

我有一个SVG字符串，如下面的代码示例所示。我用它作为背景图片。

为了将其转换为我正在下面执行的图像：

 var asImage = "data:image/svg+xml; base64," + window.btoa(unescape(encodeURIComponent(markupDataStr)));

但问题是，SVG包含一些中文文本測試。当我运行encodeURIComponent和unescape时，它会将中文文本转换为一些不可读的字符，例如æ¸¬è©¦。

但是在这个例子中，它并没有改变上面的文字。我在这里错过了什么吗？

＆＃13;

var str = window.holder.value;

var asImage = "data:image/svg+xml; base64," + unescape(encodeURIComponent(str));

console.log(str);

＆＃13;

Answer 1

使用decodeURIComponent进行编码时，请使用escape进行解码;

使用unescape进行编码时，请使用unescape(encodeURIComponent(markupDataStr))进行解码。

所以，decodeURIComponent(encodeURIComponent(markupDataStr))应该是 escape

顺便说一下，不推荐使用

Suppressed: java.lang.ClassNotFoundException: android.support.v7.appcompat.R$drawable

。

unescape将中文字符转换为不可读的内容
