HTML: insert line-break in email subject like %20 is a space?
提问by matt
BreakHere…
打破这里…
I wonder if it is possible to write something like %20(which stands for a space) for a line-break as well. So I want to have seperate lines in my body of the e-mail.
我想知道是否也可以%20为换行符编写类似（代表空格）的内容。所以我想在我的电子邮件正文中有单独的行。
Any ideas?
有任何想法吗？

You should use a carriage return %0Dand line feed %0A
您应该使用回车%0D和换行%0A
<a href="mailto:[email protected][email protected]&subject=your subject&body=Text before new line.%0D%0AText after new line.">create email</a>
This is defined in RFC2368and is the only valid method of generating a line-break.
这在RFC2368中定义并且是生成换行符的唯一有效方法。

Replace \n(and \r\n) by %0D%0Aas specified by RFC6068(in section 5) updating the mailtoURI Schemeas of October 2010 (replacing RFC2368).
替换\n（和\r\n）由RFC6068（在第 5 节中）%0D%0A指定，更新截至 2010 年 10 月的URI 方案（替换RFC2368）。mailto
[...] line breaks in the body of a message MUST be encoded with
"%0D%0A".
Implementations MAY add a final line break to the body of a message even if there is no trailing"%0D%0A"in the body [...]
[...] 消息正文中的换行符必须使用
"%0D%0A".
即使正文中没有尾随"%0D%0A"[...]
This is the example from the RFC (in section 6)
这是来自 RFC 的示例（在第 6 节中）
<mailto:[email protected]?body=send%20current-issue%0D%0Asend%20index>
The above mail body corresponds to:
上述邮件正文对应于：
send current-issue
send index
