Subject [jira] Created: (PIG-1187) UTF-8 (international code) breaks with loader when load with schema is specified

UTF-8 (international code) breaks with loader when load with schema is specified
--------------------------------------------------------------------------------

                 Key: PIG-1187
                 URL: https://issues.apache.org/jira/browse/PIG-1187
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.6.0
            Reporter: Viraj Bhat
             Fix For: 0.6.0


I have a set of Pig statements which dump an international dataset.
{code}
INPUT_OBJECT = load 'internationalcode';
describe INPUT_OBJECT;
dump INPUT_OBJECT;
{code}

Sample output

(756a6196-ebcd-4789-ad2f-175e5df65d55,{(labelAaÂâÀ),(labelあいうえお1),(labelஜார்க2),(labeladfadf)})

It works and dumps results but when I use a schema for loading it fails.

{code}
INPUT_OBJECT = load 'internationalcode' AS (object_id:chararray, labels: bag {T: tuple(label:chararray)});
describe INPUT_OBJECT;
{code}
