Customize whitespace characters/markers on GtkSourceView
I am using Gtk3+ and Python 2.7
Have implemented GtkSource.view to display whitespace characters/markers.
After setting View.set_draw_spaces(GtkSource.DrawSpacesFlags.ALL), it is displaying whitespace characters, But I want to redraw/customize some symbols like Non-Breaking space, Non-Breaking Hyphen, Zero-width-space ,and make Breakpoint symbol smaller.
But how to customize/redefine/redraw these characters or to extend/redefine GtkSourceView methods.source_View_draw.py
