'HTML: insert line-break in email subject like %20 is a space?

<a href="mailto:[email protected]?subject=Whatever%20this%20is &body=HowcanIaddLine<br/>Break here

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 separate lines in my body of the e-mail.

Any ideas?



Solution 1:[1]

Replace \n (and \r\n) by %0D%0A as specified by RFC6068 (in section 5) updating the mailto URI Scheme as of October 2010 (replacing RFC2368).

[...] 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 [...]

This is the example from the RFC (in section 6)

<mailto:[email protected]?body=send%20current-issue%0D%0Asend%20index>

The above mail body corresponds to:

send current-issue
send index
