I want to show weird code/character on textbox winform

I have no idea how to show weird character code. example \n, \u0003. I want to show it "\n" or "\u0003" on textbox, i.e. I don't want to show the symbol itself but its code.

any idea?

thank you so much

If you want to encode the string, i.e. to represent control characters with their codes (for instance for some kind of logging, debugging etc.)

  using System.Linq;

  ...

  private static string Encode(string value) {
    if (null == value)
      return null;

    return string.Concat(value
      .Select(c => char.IsControl(c) 
         ? $"\\u{((int) c):x4}" // control symbol - as a code
         : c.ToString()));      // non-control    - as it is
  }

Then 

  myTextBox.Text = Encode("abc\ndef\r\t566");

And you'll have

  abc\u000adef\u000d\u0009566
