Multibyte language support on Microsoft SQL Server
If you support multibyte languages, you must verify the data source property settings on your WebSphere® Application Server Liberty profile or WebSphere Application Server.
New installations of IBM® TRIRIGA® require Microsoft SQL Server databases that support multi-language. In an upgrade scenario, you can continue to use a single-byte Microsoft SQL Server database. However, be advised that support for upgrading IBM TRIRIGA deployed on single-byte Microsoft SQL Server databases will be deprecated in a future release.
If you have WebSphere Application Server, in the data source, the custom property of sendStringParametersAsUnicode must be set to true.
