If you Unicode-enable an OpenEdge database represented by an ANSI code page, you must consider the impact of potential data widening when that data is converted to Unicode during migration. You should also consider the impact of any future data widening if data from certain locales is expected to increase the byte count of your data. These implications are further discussed in OpenEdge DB-to-Oracle utility. Specific considerations for handling character length are discussed in Handling character length during database migration.
