Does ERwin support Character Set in Unicode format?
Check the Character Set in the Column Editor to see if it has Unicode as an available choice. Also, this is database specific so will need to know the database and version. In general, only ANSI is supported and Unicode is not. That is why SQL Scripts from SQL Server (or other databases), must be saved in MS-DOS text. Alternately, the file can be saved in Notepad (or any other text editor) in ANSI format.
