�在 Base64 编码的电子邮件中

Question

我在使用瑞典语 + MS Outlook 时遇到问题。

除了 MS Outlook 之外，它在任何地方都运行良好。在 MS Outlook 中，瑞典语字符显示为 �。电子邮件内容采用 base64 编码、uft-8 等。可能有什么问题？

粘贴的消息源的 Content-Type: 标头中间似乎有一个虚假的换行符。它应该是一条逻辑线；尽管您可能粘贴错误（已接收：标头至少没有正确粘贴）。在 Base64 主体部分中似乎也发生了类似的情况——我们在数据行之间看到空行。

它看起来像这样：

Content-Type: multipart/mixed;

boundary="=_41bea315b9b2f2301a97632f8d6c3057"

应该是：

Content-Type: multipart/mixed;
   boundary="=_41bea315b9b2f2301a97632f8d6c3057"

在“boundary”关键字之前至少有一个空格字符；或者甚至

Content-Type: multipart/mixed; boundary="=_41bea315b9b2f2301a97632f8d6c3057"

此外，如果主题行包含 8 位数据，则​​应该对主题行进行 RFC2047 编码。

Subject: =?utf-8?Q?Ny_best=C3=A4llning_har_kommit_in_fr=C3=A5n_ace_Best=C3=A4llnings-ID:_FA12914-1?=

删除换行符后，正文部分中的 base64 数据看起来是正确的，即单词“Beställning”显示正确（尽管它应该正确地不正确大小写；也许有一个瑞典.stackexchange.com 可以对您的副本进行批评？： -)

X-Mailer: 标头表明您正在使用某个软件生成这些消息；它可能有正确执行这些操作的选项，但您没有使用它们。这是一个编程论坛，因此您可能应该向我们展示您的代码，并使用适当的编程语言标记问题。
