Pre-release 4.9 SQL Servers do not perform character set conversion. If your client application communicates with a pre-release 4.9 SQL Server but uses a different character set from the server, international characters may not be represented correctly.
To solve the problem, you can:
Change your client application’s character set to match that of the SQL Server, or
Install custom character set conversion routines using cs_manage_convert and call cs_convert to convert the data before sending it to the server.
