如何确定创建无意义字符的内容

Question

我正在尝试确定导致此错误的原因：

  Transaction Error!
  There was a problem with the transaction. 
  The credit card information was initially accepted but an auto void has been placed because of a system error. 

  Please contact the association. 

  The site administrator has been notified of the error.
  The value u^m cannot be converted to a number.

这是在处理信用卡付款期间发生的。

有没有办法知道什么转换为u ^ m，反之亦然？例如，％20转换为空格。

Answer 1

这个解决方案结果是来自cookie的值，它已经在进入cookie的过程中被加密，被翻译为u ^ m，因为它在用于创建数字时没有被解密。
