SAS uses the default
session encoding when referencing external files and directories.
The PATHENCODING environment variable provides an alternative encoding
for external file and directory references. PATHENCODING is valid
only for files that are located on disk. When the PATHENCODING environment
variable has a valid encoding value, SAS transcodes the pathname in
the specified encoding.
For a list of valid
encoding values on UNIX, see UNIX Encoding Values in SAS National Language Support (NLS): Reference Guide.
