Local fix

• N/A
  

Problem summary

• When the XML Schema validator computes the length of a
  string in characters it does so using String.length() instead of
  
  counting the number of Unicode code points. With String.length()
  a
  surrogate pair (representing a single character) is counted as
  two
  characters instead of one.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR12
  6.0.1 SR4
  .
  Introduced a system property for controlling how
  string length is computed by the schema validator. When
  
  org.apache.xerces.impl.dv.xs.useCodePointCountForStringLength is
  set to
  true, the length of an xs:string or xs:anyURI value is
  calculated by
  counting the number of Unicode code points in the string. The
  value of
  the system property is false by default, preserving the long
  standing
  behaviour of computing length in Java chars (i.e.
  String.length()).     .
