我正在使用 Zend Framework 2 发送电子邮件，使用布局并正确设置<META content="text/html; charset=UTF-8" http-equiv=Content-Type>标签<head>。
当我在电子邮件内容中放置包含 IP 地址的链接时，Outlook（365 版）无法正确识别字符集，并以西欧（Windows）编码显示电子邮件。
当然，如果我在操作 -> 其他操作 -> 编码中将编码更改为 UTF-8，它就会正确显示。
您是否知道如何强制 Outlook 以 UTF-8 显示电子邮件？
当我将链接更改为不包含 IP 地址时，Outlook 可以正确识别 UTF-8 编码，唯一的问题是当链接包含 IP 地址时。
我检查了一下，发现只有$this->serverurl()方法存在问题，但鉴于 IP 地址是硬编码的，效果是一样的：无法识别 UTF-8。
电子邮件内容（不含布局）：
<?php
echo sprintf(
$this->translate('scp.notification.done'),
'<a href="'.$this->serverurl() . $this->url('system-change-proposal/view', array('id' => $this->id)) . '">' . $this->info['PROPOSAL_NUMBER'] . '</a><br/>',
$this->info['CREATE_DATE'] . '<br/>',
$this->info['TOPIC'] . '<br/>',
$this->info['CONTENT']
);
?>
电子邮件显示如下（波兰语，带有损坏的波兰语变音符号）：

在生产服务器上将$this->serverurl()输出正常地址，但在测试服务器上它将始终输出 IP 地址，这不应该（但目前确实）破坏编码识别。
我检查了一下，在 Webmail 中，问题与 Outlook 中的问题相同，而 GMail 则正确显示它。
也许这可能是 IMAP 服务器配置问题？我对这类事情一无所知。
我在 Stackoverflow 上问了同样的问题，但经过考虑，我认为它更适合在这里。
