The problem is I don't know how to remove the square character because it is not a conventional ASCII character.

char Sq; //Hardcode it here!!
While(MyString.IndexOf(Sq) != -1)
    MyString.Remove(MyString.IndexOf(Sq), 1);

The reason for this I believe is because C# doesn't recognise the character as a newline, but simply a character in the shape of a square.

When I copy and paste the symbol into a .net environment it just pastes a newline (ie, like it would I key return).

I would like these events to be raised on the main thread
