You made a very good guess, then! Mail like this is the
preferred way to report cwm bugs.

Yes, I have reproduced the problem.

it does for me. Hmm...

I reduced your decoy.n3 file to a small test case:

  http://www.w3.org/2000/10/swap/test/utf8lit.n3
  $Id: utf8lit.n3,v 1.1 2002/06/28 16:15:39 connolly Exp $

It won't be in the regression suite (swap/test/retest.sh)
until we fix the bug.

I'm not sure I have time to hunt it down soon;
let me know if you find the bug or a patch.

Hmm... that doesn't sound right.

You were doing so great on bug-reporting-protocol until here. 1/2 ;-)

Each bug report and feature request belongs in its own message,
please.

I'll reply to the feature request separately.
