Yeah, I thought it was that problem and was allready trying to figure it out.
I come up with the following additional patch:

But what should we do with glib2, which seems to not enable all features with
the native iconv?

Juha-Matti Tilli gave me this example:

% /usr/bin/iconv -f iso-8859-15 -t ascii//translit
iconv: iconv_open(ascii//translit, iso-8859-15): Invalid argument

I agree.

The best would if the citrus iconv would support the needed things for irssi.
