HTML Carriage Return on mailto string

I making an html to send an email with mailto: command. The procedure is i made a function:

raceracerace=""
raceracerace=raceracerace + "any string"
raceracerace=raceracerace + "any string2"

function emailrace(){

location.href = 'mailto:[email protected]?subject=' + 'subect' + '&body=' + raceracerace;

}

but in the middle of:
raceracerace=raceracerace + "any string"
raceracerace=raceracerace + "any string2"

I need to put a carriage return to put that result on my body of mailto command like is on my funtcion i tried this and not work:

raceracerace=raceracerace + "any string" + "'"
raceracerace=raceracerace + "any string2"

I tried this too and nothing:
raceracerace=raceracerace + "any string" + "<br>"
raceracerace=raceracerace + "any string2"

Anyone know how to put a carriage return where i need? All of the rest is working perfect my function and all only is the carriage return on the string.

I have another issue maybe someone can help me. I have the string but now i want to kind of encrypt or something like that my variable raceracerace to after send the mail decrypt. Somenoe know how to do that? Thank you

Encryption from the client-side is worthless. Anyone can see how it is being done. True security must come from the server-side.
