"Doens't help" in what sense? It should convert the ISO-8859-1 
to UTF-8. Which is genererally what you'd want in a GTK+-2.0 app.
(But remember, that you're users won't all be using ISO-8859-1)

Note that the default for GIOChannel is UTF-8, if you want no
conversion, you need to set the explicitely.

This is described in:
