Not able to read special character “£” using Streamreader in

Question

I am trying to read a character (£) from a text file, using the following code:

public static List<string> ReadAllLines(string path, bool discardEmptyLines, bool doTrim) {

var retVal = new List<string>();

if (string.IsNullOrEmpty(path) || !File.Exists(path))
{
     Comm.File.Log.LogError("ReadAllLines", string.Format("Could not load file: {0}", path)); return retVal; }

//StreamReader sr = null;

StreamReader sr = new StreamReader(path, Encoding.Default));

try {
sr = File.OpenText(path); while (sr.Peek() >= 0)
{
var line = sr.ReadLine();
if (discardEmptyLines && (line == null || string.IsNullOrEmpty(line.Trim())))
{
continue; }
if (line != null) { retVal.Add(doTrim ? line.Trim() : line);
}
}
}

catch (Exception ex)
{
Comm.File.Log.LogGeneralException("ReadAllLines", ex);
}
finally
{
if (sr != null) { sr.Close();
}
}
But my code is not correctly reading £, It is reading the character as ? please guide me what needs to be done to read the special character.
And My text file is::
108|25|50001408|4|6.95|£
108|25|50001392|4|5.23|£
108|25|50001385|3|5.29|£
108|25|50001378|3|14.25|£
Thanks in advance.
