Part 4: The Connect XE Drivers : The Driver for the Teradata Database : Unicode Support

Unicode Support
The driver supports Unicode data types. The following table shows how the Teradata data types map to the Unicode data types, but only when CharacterSet is set to UTF-16.
The driver supports the Unicode ODBC W (Wide) function calls, such as SQLConnectW. This allows the Driver Manager to transmit these calls directly to the driver. Otherwise, the Driver Manager would incur the additional overhead of converting the W calls to ANSI function calls, and vice versa.
See UTF-16 Applications on UNIX and Linux for related details. Also, refer to "Configuring the Product on UNIX/Linux" in the DataDirect Connect Series for ODBC Reference for a more detailed explanation of Unicode.
