奇怪的URI字符“％f0％9f％8c％b4％f0％9f％9a％8c％f0％9f％90”

Question

我试图弄清楚这个网址中编码的字符是什么： http://whatyouth.com/9236/roadtripppp-%f0%9f%8c-%b4%f0%9f%9a-%8c%f0%9f%90-roadtrip-throwback-again-sorry-missingsummer-palmtrees-rememberwhatyouth/

当我使用javascript函数decodeURI时，我收到此错误：

decodeURI("http://whatyouth.com/9236/roadtripppp-%f0%9f%8c-%b4%f0%9f%9a-%8c%f0%9f%90-roadtrip-throwback-again-sorry-missingsummer-palmtrees-rememberwhatyouth/")
> URIError: URI malformed

有人知道这些角色是什么吗？

• %f0%9f%8c
• %b4%f0%9f%9a
• %8c%f0%9f%90

Answer 1

我想这是一个Windows-1252编码：ASCII Encoding Reference (W3Schools)（对不起W3Schools链接...不是我最喜欢的网站）

我在我的网址中用'\ x'替换了每个'％'，我在这个答案中使用了函数：https://stackoverflow.com/a/4129920/3484498

decodeBytes(url,'cp1252');
