User-defined session character sets can be used either with or without a translation DLL. If no translation DLL is specified, the driver's conversion is based on the current application code page. With Teradata-provided session character sets, no translation DLLs are needed as long as the session character set matches to the current application code page. For example, a Chinese session character set matches the Chinese Windows PC.
Teradata recommends that translation DLLs be copied to the same folder and location where the driver was installed.
