Well '\n\r' does not mean "newline" literally "backslash n backslash r".
Everything in single quotes is used without any substitudion of escape
sequences or avariables. You have to use double quotes if you want to
pass CR/LF using \r\n.
Also you must not wrap a string over multiple lines with spaces in
between. So a better way:
QRcode::png("BEGIN:VCARD\r\n".
"VERSION:3.0\r\n".
"N:Gump;Forrest\r\n".
"FN:Forrest Gump\r\n".
"TEL;WORK;VOICE:(111) 555-1212\r\n".
"TEL;HOME;VOICE:(404) 555-1212\r\n".
"REV:20130116T195243Z\r\n".
"END:VCARD",
'promo/QR/test.png');

"L" is the ECC level. You can pass this as parameter.
