Subject [jira] [Commented] (AVRO-860) Invalid JSON when printing out records with unicode
Date Fri, 15 Jul 2011 21:48:05 GMT

    [ https://issues.apache.org/jira/browse/AVRO-860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066231#comment-13066231
] 

Scott Carey commented on AVRO-860:
----------------------------------

It could be as simple as creating a very simple GenercData.Record with a string field set
to have the "™" in there (you can place unicode utf8 directly in the source, or use a \u
literal).
{code}
Schema s = Schema.parse("{\"type\":\"record\", \"fields\": [{\"name":\"bar\", \"type\":\"string\"}]}");
GenericData.Record foo = new GenericData.Record(s);
foo.put(0, "utf8 trademark char-> ™ <-");
Assert.assertEquals(expected, foo.toString());
{code}

> I have an avro file, that when printed returns invalid JSON.
> The code for iterating and printing is:
> {code}
>             DatumReader<GenericRecord> reader = new GenericDatumReader<GenericRecord>();
>             DataFileReader<GenericRecord> dataFileReader =

>                 System.out.println(dataFileReader.next().toString());
>             }
> {code}
> and the relevant JSON snippet is
