Those characters have no mapping in ASCII. Review an ASCII table, like Wikipedia's, to verify this. You might be interested in the Windows 1252 encoding, or "extended ASCII", as it's sometimes called, which has code points for many accented characters, Spanish included.

var input = "La introducción masiva de las nuevas tecnologías de la información";
var utf8bytes = Encoding.UTF8.GetBytes(input);
var win1252Bytes = Encoding.Convert(
                Encoding.UTF8, Encoding.GetEncoding("windows-1252"), utf8bytes);
File.WriteAllBytes(@"foo.txt", win1252Bytes);
