PM21520: THE CODE FOR CONVERTING A RANGE OF BYTES FROM UTF8 TO UTF16 FOR A NON-UTF8 RESULT WAS INCORRECT IN THE XCI SERIALIZER

APAR status

• Closed as program error.

Error description

• The code for converting a range of an array of UTF8 bytes to
  UTF16 when serializing to a non-UTF8 result was incorrect and
  would corrupt the output when the UTF8 array contained
  non-ASCII, for example, multi-byte, characters.

  * PROBLEM DESCRIPTION: Incorrect UTF8 to UTF16 conversion      *
  *                      during serialization of a subrange of   *
  *                      a UTF8 array when writing to a          *
  *                      non-UTF8 result.                        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The code incorrectly assumed that offsets in UTF8 byte arrays
  would be the same as the offsets in the UTF16 char array result
  after conversion from UTF16.  This is only true when the UTF8
  input only contains US-ASCII code points.
  

Problem conclusion

• The code was rewritten to use the proper methods to convert
  the range of the UTF8 input into UTF16 and use the correct
  range of the result.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.9.  Please refer to the Recommended Updates
