Gtk in spanish again

["J.Eusebio Roza" <eusebio roza uah es>]

Hi!
I use gtk 1.3  in windows and my program begin with gtk_init() and
gtk_set_locale(); I have a gtk_text widget when i can write in spanish
characteres but i can not open an spanish file and show it (lines with
spanish characteres are not shown). I can not write a label in spanish
too, but i can write in a gtk_entry.
am i crazy?
when is my problem?

Thanks a lot...
