GIOChannel does have something to do with the encoding as it will invoke
iconv on your behalf. The functions on the interface are
g_io_channel_{get,set}_encoding. The conversion is always to UTF-8,
which what everything thing else in GTK+ libs expects.

But it does. GIOChannel has some pretty fairly high level conveniences
tailored for GTK+ application developers.
