To enter a copyright or phonogram symbol as part of the data in a record, position your cursor appropriately, and either use the Edit menu or Function keys, as shown below
Be aware that, the phonogram symbol will not display correctly in RIMMF at this time (this is because RIMMF doesn't yet support the display of unicode characters). However, the data that is entered using <Shift><F2> will display correctly in other programs that support unicode.
