RE: HELP for TextView functions

The reason for this, is that your text is not valid UTF8.  All of GTK uses UTF8.  You can check the validity of your text using this function: g_utf8_validate();

http://developer.gnome.org/doc/API/2.0/glib/glib-Unicode-Manipulation.html#g-utf8-validate
  
Look at the gtk-demo for an example on how to use the GtkTextView widget.
