  * PROBLEM DESCRIPTION: Invalid UTF-16 values specified in the  *

  *                      being flagged as in error.              *
  *                                                              *

  ****************************************************************
  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.
