Steve Hawkins resolved TEIID-1021.
----------------------------------

    Fix Version/s: 7.0
                       (was: 7.1)
       Resolution: Done


Added the system functions encode/decode that can convert between blob and clob values.  The accepted encoding must be a string literal and is validated against the known java encodings.  A follow-up feature to this work would be to add encoding support for base64 and hex as well.

> I was working with a Japanese PostGreSQL database - database encoding is SQL_ASCII, but some of the columns have EUC_JP encoded data.  I attempted to create a UDF to utilize the PostGreSQL convert(string, sourceEncoding, targetEncoding) function, but had difficulty with that (in the production version 554).  Eventually we were able to workaround with other code changes, but handling of this situation may have been easier with a byte data type - logging this JIRA for consideration in teiid.
