Question

I’ve a .txt file which has control characters associated with email address.Some thing line this @ãgmail.com. There might be multiple instances of this and multiple instances of other control characters . Is there a way I can first find them and then remove them?

Answer 1

a piece of c# code – not very optimized for large count of control characters. a hint for starting:

StreamReader sr = new StreamReader(@"c:\temp.data\big_file_with_unwanted_chars.txt", Encoding.Default);
StreamWriter sw = new StreamWriter(@"c:\temp.data\big_file_without_any_evil_chars.txt", false, Encoding.Default);

string al;

while (!sr.EndOfStream)
{
  al = sr.ReadLine();
  al = al.Replace("ä", "");
  al = al.Replace("#", "");
  sw.WriteLine(al);
}
sw.Close();
sr.Close();
