Encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, or three escape sequences representing the UTF-8 encoding of the character
通过用一个、两个或三个表示字符的 UTF-8 编码的转义序列替换某些字符的每个实例，对统一资源标识符 (URI) 组件进行编码
Which means, in order to encode a pound sign, JavaScript uses 2 characters.
这意味着，为了对井号进行编码，JavaScript 使用 2 个字符。
￡ = %C2%A3

It would be best to use %C2%A3 in place of the pound sign in your script.
最好使用 %C2%A3 代替脚本中的井号。
