我正在使用 Pyramid 框架，试图将 UTF8 数据发布到它。这是我得到的例外。我不确定如何解决这个问题。任何想法为什么会发生？

它窒息的字符串是“Venus\xe4gen”。

我正在从使用这些属性定义的 HTML 表单中提交数据：

<form name="form_reg" id="formtrans" method="post" action="signup"
        content="text/html; charset=utf-8">

好的，伙计们，我似乎找到了问题所在。问题是表单是基于 PHP 的服务器。它使用 cURL 将数据从一台服务器发布到另一台服务器。第二台服务器有 Pyramid 应用程序，它接受请求。我添加了 iconv('ISO-8859-1','UTF-8',$fields_string) 并修复了它

            $fields = $_REQUEST;

            foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
            rtrim($fields_string,'&');                
            //open connection
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_HTTPHEADER, "Content-Type: text/html; charset=utf-8");

            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_POST, count($fields));
            $fields_string = iconv('ISO-8859-1', 'UTF-8', $fields_string);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);

            $result = curl_exec($ch);
            curl_close($ch);

我不确定为什么 PHP 会这样，$_REQUEST 应该是 UTF-8，因为页面的字符集（元也是）是 utf-8。虽然我不是 PHP 的忠实粉丝。感谢大家的帮助！
