Currently, column names with strange characters (e.g. diacritics) cannot be used and will be skipped when adding them to Local Subject Areas.
My customer is using localized strings to show custom names and descriptions, based on language setting. To identify the source of columns we also use an asterisks (*) in some cases. The column in RPD itself, does not have these asterisks and classic view is perfectly fine with this, but unfortunately, these columns cannot be used to create a local subject area in DV.
It would be great to have this limitation removed in a next release.
thanks, Erik
