PyGtk, What are The Hidden Chars in TextView?

Question

i meet a problem when i used get_text(start_iter, end_iter, include_hidden_chars) method of Gtk TextBuffer object. i didn't understand include_hidden_chars arg what it is and what it does? can you give simple example about hidden chars in Gtk TextView?

Thanks

You can set some invisible text in the text buffer by using a text mark that sets the "invisible" property to true [1]

When you use the get_text method of the buffer you can decide if the method should or shouldn't include the hidden text in the return value
