The “test” we're discussing here is:

    mkdir br1; cd br1; bzr init .; touch més; ln -s més prova; bzr add prova;
    bzr commit -m "link to utf-8 file name"; cd ..; bzr branch br1 br2

(from <https://bugs.edge.launchpad.net/bzr/+bug/272444/comments/1>)

So not part of the test suite.  It does give a good demonstration of the perils
of testing in anything but a precisely controlled environment, though :)
