When I use korean character by view index key, no result

View Index Create
CREATE INDEX ix_default_1 on default(COL_1, COL_6) USING View;

Can I execute query using korean character by view index key?
Is there anyone who knows similar issues?

I can’t answer you the question in regards to N1QL. I’d just like to mention that if your queries don’t need to full power of N1QL and can be solved with a mapreduce view, you might want to use those instead. There Korean should work fine (as Unicode is supported there).

I also confirmed that Korean support is available by the MapReduce view without N1QL.
But, view index of N1QL seems to not be supported Korean.
