Sorry for the delay in responding.  It would likely be a while before
I could take a look at this -- and I suspect the other developers
are busy, too.  If you could get an initial patch working then it
would likely find it's way into swish a lot sooner.

I have not looked at the new API, but if it requires utf8 on input then
we would need to use iconv to convert from swish-e's 8859-1 to utf8
and back again.  Look also at parser.c to see how swish uses libxml2's
method to convert utf8 to latin1.

Maybe someone else on the list with C skills would be interested in
helping?  Anyone?
