That doesn't work:
>>> import gtk
>>> tv = gtk.TextView()
>>> b = tv.get_buffer()
>>> t = "test\x00"
>>> u = unicode(t, 'utf-8')
>>> b.set_text(t)
__main__:1: GtkWarning: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed
it's the same if I try with the unicode:
>>> import gtk
>>> tv = gtk.TextView()
>>> b = tv.get_buffer()
>>> t = "test\x00"
>>> u = unicode(t, 'utf-8')
>>> b.set_text(u)
__main__:1: GtkWarning: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed
