The test suite is currently distributed as a zip file. It so happens that the file concerned is named using ISO-8859-1 on the distributors system. On my system, doing ls from the GNOME console shows the name as xgespr?ch.xml. Whereas Emacs dired shows the name as xgespräch.xml.
Zip files treat filenames as byte arrays, so zip tends to be clumsy when you get zipfiles created on legacy systems. Its compatible with utf-8 at least, so zipfiles you make yourself should have no problems.
So I went back to LANG=en_GB.UTF-8, unzipped the distribution again, and re-named the file, thanks to your help. ls now shows the correct file name. Emacs shows xgespräch.xml. And the test works.
I tried emacs and saw the same problem you did. vim seems to work correctly with locales. Allthough advising a switch to vim is probably more responsible, a quick seach revealed this link: http://linux.seindal.dk/item32.html
Has anyone any illuminating comments to make? I'm particularly interested in the distribution problem.
You could have the distributor change his locale to utf-8 and rename the files on his filesystem.
