Use ASCII client collation when executing analytic functions. If your data has UNICODE characters, set the UTF8 client character set and Collation set to ASCII for the user session.

Multinational Collation
If the user session collation is set to Multinational, analytic functions may report an error in certain situations. Best practice is to do the following:
- Reduce the size or number of input and output fields.
- Remove ORDER BY from larger output data fields.
- Run the query with the user session collation set to ASCII.
