En la linea numero 13 se establece la nota de aviso para el lector que aparecera en el cuerpo del mensaje. 
Si no deseas que aparezca ningun aviso, deja la linea de esta manera: define (“mensaje”, “”);
Otra opcion para que no aparezca ningun aviso consiste en borrar la linea n? 13 y borrar tambien la linea numero 36 ($devolver .= mensaje;)
NOTA: Los caracteres con tildes y otros como la ? quedaran en may?sculas tras las transformacion.
