             Summary: Grouping on reduce views tests for equality rather than ICU equivalence
                 Key: COUCHDB-1805
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1805
             Project: CouchDB
          Issue Type: Bug
            Reporter: Adam Kocoloski


If I emit keys from two documents that are distinct but compare equal from ICU's point of
view, a group=true query over the view will show two distinct rows.  I think the expected
behavior is that the rows are combined when ICU collation says the keys compare equal.

I think part of the fix is to modify the group_rows_fun to call out to ICU instead of doing
a simple == comparison:
