Although are also gint8/guint8 types in GTK+, gchar/guchar have
been used extensively to mean 8-bit integers, so I think changing
them isn't really feasible at this point; it would be better to
introduce a new gwchar type.

In addition, because UTF-8 will be a very common external interface,
we still need 8-bit character data, even with Unicode. In fact,
my current feeling is that at least the external interfaces for
GTK+ should be defined as UTF-8 - they should not be converted
to wide characters.
