APAR status

• Closed as program error.

Error description

• Some EXSLT String module extension functions do not handle
  Non-ASCII XML characters properly.
  
  Affected functions are "str:padding", "str:split" with empty 2nd
  argument and "str:align".
  

Local fix

• Use str:tokenize(_,'') instead of str:split(_,'').
  For str:padding() and str:split(), none.
  

Problem summary

• Affected is the use of "str:padding", "str:split" with empty
  2nd argument and "str:align" EXSLT extension functions.
  
  These functions do not handle Non-ASCII XML characters
  correctly; these are samples for wrong behavior:
  
  str:padding(11,'𐀈𐀉𐀊')
  str:split('$¢€𐀈', '')
  str:align('¢€',
  '𐀈𐀉𐀊𐀋𐀌', 'center')
  

Problem conclusion

• The fix is available in 3.8.2.17, 4.0.1.15, 4.0.2.11 and 5.0.0.5
