Problem summary

  • ****************************************************************
    * USERS AFFECTED: Enterprise PL/I users who feed invalid       *
    *                 UTF-16 value to the built-in functions       *

    * PROBLEM DESCRIPTION: Invalid UTF-16 values specified in the  *
    *                      UTF-16 built-in functions are not       *
    *                      being flagged as in error.              *
    *                                                              *
    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF.                      *
    *                                                              *
    ****************************************************************
    If a UTF-16 value is in the range from 'd800'wx through
    'dbff'wx, it must be followed by a UTF-16 value in the range
    'dc00'wx through 'dfff'wx, but the code was accepting any second
    value that was 'dc00'wx or greater.
    In addition, the code was also accepting values in the range
    'dc00'wx through 'dfff'wx when they were not the second half
    of a surrogate pair.
    

Problem conclusion

  • The tests in the code were incomplete and should have flagged
    the above invalid source values as invalid. The library code
    has been corrected.
