ASCII is a 7-bit encoding and has no 'Ñ'. In order to have that character,
your file must use an encoding other than ASCII. You must discover what
that encoding is and tell the StreamReader. By default it uses
UTF8Encoding.

Try
  StreamReader sr = new
StreamReader("foo.txt",System.Text.Encoding.Default);

That will us your computer's regional settings to get the current code page,
or figure out what code page is used for your file and specify it.
