APAR status

• Closed as program error.

Error description

• DataPower extension function regexp:replace() might yield
  incorrect results when input text contains multi-byte
  characters.
  

Local fix

• Users may use XQuery's fn:replace() instead of XSLT's
  regexp:replace().
  

Problem summary

• Affected is the use of  regexp:replace()  EXSLT extension
  function.
  
  Matching should be done (unicode) character wise, but is done
  byte wise leading to wrong matches for multibyte UTF-8
  characters (UTF-8 is DataPower internal encoding).
  

Problem conclusion

• Fix is available in 6.0.0.15, 6.0.1.11, 7.0.0.8 and 7.1.0.5
