如何在邮件主题中设置umlautü [英] How to set an umlaut ü in the mail subject

问题描述

我需要生成包含变音符号的德语电子邮件。在电子邮件本身，这是完美的，但不是在电子邮件的主题。我尝试了许多不同的变音符号，除了ü，他们都似乎工作。我也试过不同的邮件库（HTMLMimeMail& PHPMailer），他们都失败了：

  $ mail = new htmlMimeMail（） ; 
 $ mail-> setTextEncoding（base64）; 
 $ mail-> setHTMLEncoding（base64）; 
 $ mail-> setTextCharset（UTF-8）; 
 $ mail-> setHTMLCharset（UTF-8）; 
 $ mail-> setHeadCharset（UTF-8）; 
 $ mail-> setSMTPParams（mailinglist_smtp_host，mailinglist_smtp_port）; 
 $ mail-> setHtml（test）; 
 $ mail-> setFrom（[e-mail]）; 
 
 $ mail-> setSubject（ï，ö，ë，ä和é工作，但添加ü它不）; 
 
 $ recipients [] =[e-mail]; 
 $ mail-> send（$ recipients）; 
  

&

 code> $ mail = new PHPMailer（）; 
 $ mail-> IsMail（）; 
 $ mail-> FromName ='test'; 
 $ mail-> From ='[e-mail]'; 
 $ mail-> AddAddress（[e-mail]）; 
 $ mail-> Subject =ï，ö，ë，ä和é工作，但添加ü它不; 
 $ mail-> Body =test; 
 $ mail-> Send（）; 
  

任何人都可以帮助我找到这个问题的根源和解决方案？

解决方案

你应该 quoted-printable 编码主题标题。

像这样：

  $ mail-> Subject ==？UTF-8？Q？ 。 quoted_printable_encode（ï，ö，ë，ä和é工作，但添加ü它不）。 ？=; 
  

PHP中引用的可打印编码： http://www.php.net/manual/en/function.quoted-printable-encode.php

编辑： $ mail-> CharSet =UTF-8; 做了这个工作。

I need to generate German e-mails which contain umlaut characters. In the e-mail itself this works perfectly, but not in the subject of the e-mail. I've tried many different umlaut letters and they all seem to work except for the ü. I also tried different mail libraries (HTMLMimeMail & PHPMailer) and they both fail at this:

$mail = new htmlMimeMail();
$mail->setTextEncoding("base64");
$mail->setHTMLEncoding("base64");
$mail->setTextCharset("UTF-8");
$mail->setHTMLCharset("UTF-8");
$mail->setHeadCharset("UTF-8");
$mail->setSMTPParams(mailinglist_smtp_host,mailinglist_smtp_port);
$mail->setHtml("test");
$mail->setFrom("[e-mail]");    

$mail->setSubject("The ï, ö, ë, ä, and é work, but when adding the ü it doesn't");

$recipients[] = "[e-mail]";    
$mail->send($recipients);

&

$mail = new PHPMailer();
$mail->IsMail();
$mail->FromName = 'test';
$mail->From = '[e-mail]';
$mail->AddAddress("[e-mail]");
$mail->Subject = "The ï, ö, ë, ä, and é work, but when adding the ü it doesn't";
$mail->Body = "test";    
$mail->Send();

Can anyone help me find the source of and the solution to this problem?

解决方案

You should quoted-printable encode the subject header.

Like this:

$mail->Subject = "=?UTF-8?Q?" . quoted_printable_encode("The ï, ö, ë, ä, and é work, but when adding the ü it doesn't") . "?=";

Quoted printable encode in PHP: http://www.php.net/manual/en/function.quoted-printable-encode.php

Edit: $mail->CharSet = "UTF-8"; did the job.
