/** The Char16 class represents a CIM sixteen bit character (char16).
    This class is a trivial wrapper for a sixteen bit integer. It is used
    as the element type in the String class (used to represent the CIM
    string type). Ordinarily Uint16 could be used; however, a distinguishable
    type was needed for the purposes of function overloaded which occurs in
    the CIMValue class.
