你能帮我快点吗？谢谢。
我遇到了同样的问题。对我来说，事实证明这是由交易描述中的某些字符和交易中的项目引起的。例如。"欧元符号"，á é ä etcetera。
似乎库没有（正确）处理此编码。
Jan 完全正确，感谢您的重要领导。
自从上周我使用新的付款表格上线以来，我一直在为这个偶尔的错误而苦苦挣扎。事实证明，许多国际地址包含包含变音符号（http://en.wikipedia.org/wiki/Diacritic）的字母。我通过在帖子数据中使用这些字符在PayPal沙箱中确认了这个问题，并反复出现您上面描述的确切错误。我也在使用您上面描述的相同库。
为了尝试解决此问题（到目前为止在所有测试中都有效），我正在以下方法中清理我的用户输入（地址行 1、第 2 行、first_name、last_name等）
