One THEN/ELSE expression in the following query has a Unicode column. The query is successful and the result data type is UNICODE because the CASE expression contains 1 Unicode column and all other literals can be successfully translated to Unicode.

   SELECT i, CASE
               WHEN i=1 THEN column_u
               WHEN i=2 THEN 'abc'
               WHEN i=3 THEN 8
               WHEN i=4 THEN _KanjiSJIS'4142'XC
               ELSE 10
             END
   FROM table_1
   ORDER BY 1;
