IZ85834: DISABLE-OUTPUT-ESCAPING NOT HANDLING SURROGATE PAIRS PROPERLY

APAR status

• Closed as program error.

Error description

• Error Message: Enable disable-output-escaping in
  xsl(<xsl:value-of disable-output-escaping="yes"
  select="$briefDescription"/>), javax.xml.transform.Transformer
  un-escape the value. For extension B character, it only
  transforms the low byte of the character into decimal value, the
  high byte value is removed. For example, for extensionB
  character U+20013, its unicode is "D840 DE0B", after the
  transforming, it changes to "&#56843;" which is the decimal
  value for "DE0B". When I tried sun JDK, it can be transferred to
  correct decimal value, that is, &#131091;.

Local fix

Problem summary

• There seems to be a bug in the XLTXE-J processor in the way we
  parse UTF-8 surrogate pairs when disable-output-escaping is
  turned on. Every time we reach a high surrogate pair character,
  we would immediately read the next low surrogate pair character
  after that but the index would only be incremented once even
  though two characters were read. So the next character
  encountered would be a low surrogate pair which of course is not
  recognized and thus explains why it was escaped
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR9
  .
  The logical for incrementing the index was modify to fix this
  problem.
  .
  To obtain the fix:
  Install build 20101002 or later
