Simplified character set conversion

In earlier releases of Adaptive Server ODBC Driver and OLE DB Data Provider, client applications and Adaptive Server communicate using the character set specified in the driver's CharSet connection property. The drivers assume that both the client applications and Adaptive Server support the specified character set. To handle cases where this is not true, additional connection properties such as NomalizeUnicodeString have been created.

To simplify character set conversion in Adaptive Server ODBC Driver and OLE DB Data Provider version 15.5, CharSet has been redefined to only specify the character set that is used to communicate with Adaptive Server. The ClientCharSet connection property has been created to specify the character set that the drivers use to communicate with client applications.

Set ClientCharset to the same value as CharSet to reproduce the behavior of Adaptive Server ODBC Driver and OLE DB Data Provider 15.0 and earlier.
