OA60042: UNICODE CHARACTER CONVERSION CCSID 937 819 UNEXPECTED OUTPUT L CONVERSION TABLE NEWLINE LINEFEED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When performing a character conversion FROM ASCII CCSID 819 to
  EBCIDC CCSID 937 with conversion TECHNIQUE RLE, the NEWLINE (NL)
  character x0A is converted to x15 EBCDIC NL and not an EBCDIC
  LINEFEED (LF) x25.
  
  Converting x15 FROM CCSID 937 back to CCSID 819 produces an
  ASCII LF (x85) however x0A was expected since the conversion
  was requested with an L conversion technique search order.
  
  Since conversions between CCSID 819 and 937 do not provide an L
  conversion technique is why the unexpected result occurs.
  
  ADDITIONAL SYMPTOMS:
  EBCDIC MBCS TRADITIONAL CHINESE (T-CH)
  

Local fix

• BYPASS/CIRCUMVENTION:
  CCSID 1371 can be used instead of 937 to receive the desired x25
  character.
  
  CCSID 1371 is considered the growing CCSID which receives
  updates when new characters are added to the code page,
  where CCSID 937 is a code point which is fixed and will not
  change if new characters are added.

  * USERS AFFECTED:                                              *
  * Users of Unicode Services explore the                        *
  * conversion from CCSID 937 to CCSID 819.                      *

  * PROBLEM DESCRIPTION:                                         *
  * There was no L technique that supported                      *
  * the conversion from CCSID 937 to CCSID                       *
  * 819. This made it impossible to convert                      *
  * x'15' to x'0A' when x'0A' was expected.                      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Unicode Services should provide L technique that supports the
  conversion from CCSID 937 to CCSID 819 to convert x'15' to
  x'0A' with L technique.
  

Problem conclusion

• After the ++PTF is applied, one L table for the conversion from
  CCSID 28709 to CCSID 13488 will be added.
  Since CCSID 937 is MBCS and the conversion from CCSID 937 to
  CCSID 819 is indirect. Two steps are needed when converting
  x'15' to x'0A'with L technique:
  1. From CCSID 937 (SubCCSID 28709) to UNICODE
  The conversion from SubCCSID 28709 to CCSID 13488 with L
  technique converts x'15' to x'000A'. (The new L table will be
  loaded to do the conversion).
  2. From UNICODE to CCSID 819
  Existing conversion from UNICODE to CCSID 819 converts x'000A'
  to x'0A'.
