Please be more specific. Do you mean there are problems importing the data, displaying it, searching for it in the index, printing barcodes for items, saving titles to a list, emailing data, or something else?
All these areas have been problematic for Unicode data at one time. Some areas have been fixed, and others (especially labels) are still problematic.
