Invalid file system characters in track name (question mark for instance).
So have to remove the invalid character (?) from the track name and then export using the edit metadata tags dialog in order to set the correct track title metadata containing the character (?).
Is there a better way of working this?
Would be nice if export file names could be a separate value from the track name so that track name, and thus metadata track title, would not be limited by the file system character set.
