EmbedClob.setAsciiStream does not handle non-ascii characters correctly
-----------------------------------------------------------------------

                 Key: DERBY-2618
                 URL: https://issues.apache.org/jira/browse/DERBY-2618
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 10.3.0.0
            Reporter: Kristian Waagan
         Assigned To: Kristian Waagan


If non-ascii characters are written to the Writer returned by EmbedClob.setAsciiStream, Derby
fails with a 'java.io.UTFDataFormatException' when the CLOB value is read back.

I'm filing this bug with 'Major' priority, as the bug does not manifest itself when entering
data, just when you try to get it back. Except from filtering the data yourself before entering
it, I don't think there is any workaround.

Sample stack trace from a modified test:
