Make sure that your operating system is 8-bit clean
To support non-ASCII characters in file names, your operating system must be 8-bit clean.
An operating system is 8-bit clean if it reads the eighth bit as part of the code value. In other words, the operating system must not ignore or make its own interpretation of the value of the eighth bit.
Consult your operating-system manual or system administrator to determine whether your operating system is 8-bit clean before you decide to use a nondefault locale that contains non-ASCII characters in file names that HCL® OneDB® products use and generate.
