fix javascript code in acrobat pro to be able to bold the text send by the javascript form bottom to outlook email body

Hi,
see javascript code below (written in adobe acrobat pro javascript editor)
 
this code attached to button in pdf form . when click on the button it attached the pdf to new mail in outlook and fill the subject and the body of the email.
i need to have the body of the email BOLD  , how can i achieve this?

CODE:

// This is the form return email. It's hardcoded

// so that the form is always returned to the same address.

// Change address on your form to match the code below

var cToAddr = ""


// First, get the client CC email address

var cCCAddr = this.getField("ClientEmail").value;

// Now get the beneficiary email only if it is filled out

var cBenAddr = this.getField("BennyEmail").value;

if(cBenAddr != "")

cCCAddr += ";" + cBenAddr;

// Set the subject and body text for the email message

var cSubLine ="return protocol for fix - " + " company name: " + this.getField("company name").value  + " , " + " branch number: " + this.getField("branch name").value + " , " +  " account number: " + " " + this.getField("account number").value

var cBody = "Hi,\n\n Please see hed protocol"

 

// Send the entire PDF as a file attachment on an email

this.mailDoc({bUI: true, cTo: cToAddr, cCc: cCCAddr, cSubject: cSubLine, cMsg: cBody});

}
else {
}
