Ruby on rails 如何解决“问题”；无效的查询参数"；Rails应用程序中的错误？

一个用户最近在注册我们的网站时触发了一个错误

我试图重现这个错误，但没有成功。我知道“é”字有问题。对于这个特定的用户来说，它并没有被识别出来，但对于其他许多用户来说，它已经被识别出来了

从他的用户代理，我知道他在IE11上有这个错误

这是错误的跟踪：

An ActionController::BadRequest occurred in registrations#new:

  Invalid query parameters: Invalid encoding for parameter: Martin�

Request:

我还可以访问以下两个参数：

* rack.request.query_string                      : &name=Martin_

我想理解为什么这个错误出现在这个特定的用户身上，而不是出现在名字中带有重音的其他用户身上。它可能与浏览器或邮箱相关吗？有没有办法解决这个问题？

可能是因为：你必须在互联网上挖掘这个主题以获取更多信息。您可能可以在提交新记录之前使用

before_action

检查您的参数来解决此问题，但实际上无法提供进一步帮助，因为我以前没有这方面的经验。雪人在编码错误方面也有同样的问题。你能分享一下你的解决方案吗，@benjamin？不幸的是，我在这个问题上一直没有找到解决方案。当我不再为那家公司工作时，我不再面对这个问题。也许你可以试试Maxence说的话，但不确定它是否能解决这个问题@团滩
