sir If you use unicode charector or conversion then can possible

1 solution

Okay, there is a simple way that you can "fake" this relatively easy but depending on the width of the alternate characters and how they map into the width of the current characters, there may be a bit of a jarring interface. The trick is to overlay two TextBoxes over each other. The top one accepts the input but is, effectively, invisible. The one underneath is the one that displays your actual content. The XAML looks a bit like this:
  <TextBox Text="{Binding ConvertedText}" />
  <TextBox Foreground="Transparent" Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}" Background="Transparent" />
Now, the ViewModel behind this couldn't be simpler. Effectively, when you change the Text property, it automatically triggers the conversion code.
public string Text
  get => _text;
    if (_text != value)
      _text = value;
      ConvertedText = _text.Replace("1", "y");

public string ConvertedText
  get => _convertedText;
    if (_convertedText != value)
      _convertedText = value;
And that's it, a potentially simple solution to your problem.

You might want to set Focusable="False" on the first textbox, so that users who tab through the form don't end up typing in the wrong box. :)

That's true, missed it out altogether but as I just typed the code out in the CP editor I'm pleased I got what I wrote correct.

You are going to have to look at writing something like a behaviour then, that is going to put Runs in place.
