DB2 Unicode Support in Cincom® ObjectStudio® and Cincom® VisualWorks®
Here is how the new implementation works for you:
- If you don’t set the main encoding to Unicode (either UTF16 or UCS_2), it will work as before; all existing applications will continue to work.
- If you don’t set the main encoding to Unicode but want to use Unicode columns, you can do so as well, but when binding String values, you have to set binding templates for the binding values to indicate which Strings should be encoded as Unicode. This will provide the flexibility for users to develop “mixed” applications.
- If you set the main encoding to Unicode (either UTF16 or UCS_2), no binding template is necessary and all connect strings, SQL statements, error messages, insert and retrieved Strings will be treated as Unicode.
