vte.set_encoding("TCVN") fails
I know this is a weird error and I'm pretty sure that it doesn't belong with vte, but I can't figure out a better place to start, so the story goes:
A Terminator user opened https://github.com/gnome-terminator/terminator/issues/529, and whenever he sets the character encoding to TCVN, terminator crashes and outputs the following error
gi.repository.GLib.Error: g_convert_error: Failed to open converter for charset "TCVN": U_FILE_ACCESS_ERROR (0)
(minivte.py:78968): GLib-GObject-WARNING **: 20:31:46.032: invalid (NULL) pointer instance
(minivte.py:78968): GLib-GObject-CRITICAL **: 20:31:46.032: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
Is there some language support files that the user is missing, or is there something wrong with glib?
