Carriage Return and Line Feed in Email

In the past (Classic Client) when sending emails via SMTP I used code something like this to set a carriage return and line feed in an email body:
CRLF[1] := 13;
CRLF[2] := 10;

EmailBody := 'This is the first line' + CRLF;
EmailBody += 'This is the second line' + CRLF;

I have similar code in NAV 2016 but the email has not carriage return or line feed in it. Should this work the same in NAV 2016 as Classic Client?
