It's hard to see what the problem may be without the code that you're
using to display your text in the TextView, but I can show you an
example of Hebrew being used RTL in a TextView, maybe it will help.

If you look in the source tree for Gtk2, there's a 'gtk-demo'
directory, with a file called 'textview.pl'.  You can run this
TextView demo by calling 'perl main.pl' in that directory (assuming
you have Gtk2 properly installed).  Once 'main.pl' opens up, double
click on "Multiple Views" under "Text Widget" to run the TextView
demo.  The TextView demo grabs the TextBuffer object from the TextView
and creates a bunch of tags for it, the tags are applied to the text
in the TextBuffer, and the TextBuffer is displayed in the TextView.
The specific tag that displays the Hebrew text is 'rtl_quote'.

Hope this helps...

Thanks,
