  ****************************************************************
  An incorrect result can be returned for a query that explicitly
  or implicitly invokes the TRIM, RTRIM, or STRIP scalar
  functions.
  
  The incorrect result can occur because DB2 does not properly
  save the input or trim character string's CCSID so an improper
  CCSID is used for character comparison which can then result in
  an incorrect mismatch.
  
  The problem was reported when using MIXED character data.  For
  example if DSNHDECP specifies these settings,
  
    ENSCHEME=EBCDIC
    Japanese CCSID 930  (Japanese Extended Katakana)
    MIXED/Graphic data support
  
  the following query can return an incorrect result when the
  input string and trim character CCSIDs are not saved properly.
  
    SELECT
      RTRIM('abcd  x y z A B C X Y Z xyz',
       'abcd  x y z X Y Z xyz')      RTRIM
    FROM SYSIBM.SYSDUMMY1;
  

Problem conclusion

• The code in DB2 which supports the RTRIM functions has been
  modified to properly save the CCSIDs for both the input and trim
  strings during processing.
