Hi Kirk
Sorry, I removed the file as I manually corrected my keyword file and it works now. I replaced '75 CC 88' ('u' with 'COMBINING DIAERESIS') hex with 'C3 BC' hex ('ü').
But to demonstrate the issue, I created a new file with 1 keyword 'Zürich' with the old encoding the file had ('ü' is encoded as '75 CC 88' hex) and attached it.
Thanks for all your help and best regards
Michael
