TWideStringField is the string field class instantiated for fields of data type ftWideString. This class overrides some of the standard TField methods to handle widestring data, and introduces some properties that are only pertinent for data fields of widestring type. It should never be necessary to create an instance of TWideStringField manually, a field of this class will be instantiated automatically for each widestring field when a dataset is opened.
