gdk_draw_text is deprecated in GTK 2.0.

I would suggest drawing it with Pango, because it can handle utf8/unicode.
For example:

void my_draw_string (GtkWidget *widget, char *text, GdkGC *gc, int x, int y)
{
        layout = gtk_widget_create_pango_layout (widget, text); 
        fontd = pango_font_description_from_string ("Sans 11");
        pango_layout_set_font_description (layout, fontd);

        gdk_draw_layout (widget->window, gc, x, y, layout);

        g_object_unref (layout);
        pango_font_description_free (fontd);
}

It this case, "text" would need to be utf8. You can convert GB2312 to utf8, using
g_convert().
