> 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.
