[jira] Created: (DERBY-4902) Encoding problem in output from plan exporter

Encoding problem in output from plan exporter
---------------------------------------------

                 Key: DERBY-4902
                 URL: https://issues.apache.org/jira/browse/DERBY-4902
             Project: Derby
          Issue Type: Bug
          Components: Tools
    Affects Versions: 10.7.1.0
            Reporter: Knut Anders Hatlen
            Assignee: Knut Anders Hatlen
            Priority: Minor


If I execute a query with non-ASCII characters in it, the output from the plan exporter tool is garbled.

Example query: select * from blåbær

The HTML output looks like this in the browser: Query: select * from blåbær

Similar problem with XML: <statement>select * from blåbær</statement>

[jira] Updated: (DERBY-4902) Encoding problem in output from plan exporter

Posted by "Knut Anders Hatlen (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/DERBY-4902?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Knut Anders Hatlen updated DERBY-4902:
--------------------------------------

    Attachment: d4902.diff

The problem seems to be caused by an inconsistency in CreateXMLFile.writeTheXMLFile(). The header in the generated XML file says that the encoding is ISO-8859-1, but the code the code that produces the output uses the default encoding of the runtime environment.

The attached patch makes writeTheXMLFile() use UTF-8 consistently (and explicitly). This solved the problem for me both in the XML output and in the HTML output. The patch also adds a test case that runs cleanly with the fix, and fails with the following error without the fix:

1) testPlanExporterEncoding(org.apache.derbyTesting.functionTests.tests.lang.XplainStatisticsTest)junit.framework.ComparisonFailure: expected:<...LECT * FROM D4902_BL[ÅBÆ]R> but was:<...LECT * FROM D4902_BL[ÅBÆ]R>
